               Doctrine 2
             Not the same Old PHP ORM



Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010




    What is different in Doctrine 2?




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010




             New code, new concepts,
                different workflow




Doctrine 2    www.doctrine-project.org   www.sensiolabs.com
#sflive2010




       100% re-written codebase for
                PHP 5.3




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com

                         Are you scared?




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010




         You shouldn’t be! It is a very
          exciting thing for PHP and
           change is a good thing!



Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010




We learned lots building Doctrine
 1 and we used that to help us
        build Doctrine 2



Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010




               Let me tell you why!




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Performance of Doctrine 1



                     To hydrate 5000 records
                       in Doctrine 1 it takes
                      roughly 4.3 seconds.




Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Performance of Doctrine 2



                Under Doctrine 2, hydrating
              those same 5000 records only
                    takes 1.4 seconds.




Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Performance of Doctrine 2


              ...and with 10000 records it still
               only takes about 3.5 seconds.

               Twice the data and still faster
                      than Doctrine 1



Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Performance of Doctrine 2
• More interesting than the numbers
  themselves is the percentage improvement
  over Doctrine 1




Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                         Why is it faster?
• PHP 5.3 gives us a huge performance
  improvement when using a heavily OO
  framework like Doctrine
• Better optimized hydration algorithm
• New query and result caching
  implementations
• All around more explicit and less magical
  code results in better and faster code.
• Killed the magical aspect of Doctrine 1


Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                 Why kill the magic?
• Eliminate the WTF? factor of Doctrine 1




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010




             The Doctrine 1 magical
               features are both a
              blessing and a curse

Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Blessing and a Curse
• Magic is great when it works
• The magic you love is also the cause of all
  the pain you’ve felt with Doctrine 1
• When it doesn’t work it is hard to debug
• Edge cases are hard to fix
• Edge cases are hard to work around
• Edge cases, edge cases, edge cases
• Everything is okay until you try and go
  outside the box the magic provides
• ...magic is slow
Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

    How will we replace the magic?
      This new thing called OOP :)

•    Object Composition
•    Inheritance
•    Aggregation
•    Containment
•    Encapsulation
•    ...etc


Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

   Will Doctrine 2 have behaviors?




                             Yes and No



Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                                        The No
• We won’t have any concept of “model
  behaviors”

• Behaviors were a made up concept for
  Doctrine 1 to work with its extremely
  intrusive architecture.

• It tries to do things that PHP does not allow
  and is the result of lots of problems in
  Doctrine 1
Doctrine 2   www.doctrine-project.org      www.sensiolabs.com
#sflive2010

                                        The Yes
• Everything you can do in Doctrine 1 you can
  do in Doctrine 2, just in a different way.

• “Behavior” like functionality will be bundled
  as extensions for Doctrine 2 and will just
  contain normal OO PHP code that wraps/
  extends Doctrine code or is meant to be
  wrapped or extended by your entities.

             What did we use to build
                   Doctrine 2?




Doctrine 2    www.doctrine-project.org   www.sensiolabs.com
#sflive2010

               Doctrine 2 Tool Belt
•    phpUnit 3.4.10 - Unit Testing
•    Phing - Packaging and Distribution
•    Symfony YAML Component
•    Sismo - Continuous Integration
•    Subversion - Source Control
•    Jira - Issue Tracking and Management
•    Trac - Subversion Timeline, Source Code
     Browser, Changeset Viewer


Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Doctrine 2 Architecture
• Entities
• Lightweight persistent domain object
• Regular PHP class
• Does not extend any base Doctrine class
• Cannot be final or contain final methods
• Any two entities in a hierarchy of classes must not have a
  mapped property with the same name
• Supports inheritance, polymorphic associations and
  polymorphic queries.
• Both abstract and concrete classes can be entities
• Entities may extend non-entity classes as well as entity
  classes, and non-entity classes may extend entity classes


Doctrine 2    www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Doctrine 2 Architecture
• Your entities in Doctrine 2 don’t require
  that you extend a base class like in Doctrine
  1! No more imposing on your domain
  model!
                                namespace Entities;

                                class User
                                {
                                    private $id;
                                    private $name;
                                    private $address;
                                }

Doctrine 2    www.doctrine-project.org     www.sensiolabs.com
#sflive2010

             Doctrine 2 Architecture
• The EntityManager
• Central access point to the ORM functionality provided by
  Doctrine 2. API is used to manage the persistence of your
  objects and to query for persistent objects.
• Employes transactional write behind strategy that delays the
  execution of SQL statements in order to execute them in the
  most efficient way
• Execute at end of transaction so that all write locks are quickly
  releases
• Internally an EntityManager uses a UnitOfWork to keep track
  of your objects




Doctrine 2    www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                                 Unit Testing
• Tests are ran against multiple DBMS types.
  This is something that was not possible
  with the Doctrine 1 test suite.

•    ...Sqlite
•    ...MySQL
•    ...Oracle
•    ...PgSQL
•    ...more to come

Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                                 Unit Testing
• 859 Test Cases
• 2152 Assertions
• Tests run in a few seconds compared to
  30-40 seconds for Doctrine 1
• Much more granular and explicit unit tests
• Easier to debug failed tests
• Continuously integrated by Sismo :)




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                                         Sismo
      – No, Sismo is not available yet!!!!!!!!! :)
      – Want it? Bug Fabien!

             Database Abstraction Layer
• Separate standalone package and
  namespace (DoctrineDBAL).

• Can be used standalone.

• Much improved over Doctrine 1 in regards
  to the API for database introspection and
  schema management.



Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

             Database Abstraction Layer
• Hopefully Doctrine 2 DBAL can be the
  defacto standard DBAL for PHP 5.3 in the
  future like MDB and MDB2 were in PEAR

• Maybe we can make this happen for PEAR2?

$myTable = $schema->createTable("my_table");
$myTable->createColumn("id", "integer", array("unsigned" => true));
$myTable->createColumn("username", "string", array("length" => 32));
$myTable->setPrimaryKey(array("id"));
$myTable->addUniqueIndex(array("username"));
$schema->createSequence("my_table_seq");

$myForeign = $schema->createTable("my_foreign");
$myForeign->createColumn("id", "integer");
$myForeign->createColumn("user_id", "integer");
$myForeign->addForeignKeyConstraint($myTable, array("user_id"),
array("id"), array("onUpdate" => "CASCADE"));

$queries = $schema->toSql($myPlatform); // get queries to create this
schema.
$dropSchema = $schema->toDropSql($myPlatform); // get queries to
safely delete this schema.

                Compare DBAL Schemas


             $comparator = new DoctrineDBALSchemaComparator();
             $schemaDiff = $comparator->compare($fromSchema, $toSchema);

             // queries to get from one to another schema.
             $queries = $schemaDiff->toSql($myPlatform);

                       Things to Notice
• Entities no longer require you to extend a
  base class!
• Your domain model has absolutely no
  magic, is not imposed on by Doctrine and is
  defined by raw PHP objects and normal OO
  programming.
• The performance improvement from this is
  significant.
• Easier to understand what is happening due
  to less magic occurring. As Fabien says,
  “Kill the magic...”

                       Doctrine 2 Setup
• Setup autoloading for Doctrine classes
• ...core classes
• ...entity classes
• ...proxy classes

$doctrineClassLoader = new ClassLoader('Doctrine', '/path/to/doctrine');

                            Doctrine 2 Setup
• Create your database connection and entity
  manager

             // Database connection information
             $connectionOptions = array(
                 'driver' => 'pdo_sqlite',
                 'path' => 'database.sqlite'
             );

             // Create EntityManager
             $em = EntityManager::create($connectionOptions, $config);




Doctrine 2        www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                       Doctrine 2 Setup
• In production you would lazily load the
  EntityManager
• Example: $em = function()
             {
                                 static $em;
                                 if (!$em)
                                 {
                                   $em = EntityManager::create($connectionOptions, $config);
                                 }
                                 return $em;
                             }


• In the real world I wouldn’t recommend that
  you use the above example
• Symfony DI would take care of this for us

#sflive2010

                       Doctrine 2 Setup
• Now you can start using your models and
  persisting entities


             $user = new User;
             $user->setName('Jonathan H. Wage');
             $em->persist($user);
             $em->flush();




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                   Insert Performance
• Inserting 20 records with Doctrine

             for ($i = 0; $i < 20; ++$i) {
                 $user = new User;
                 $user->name = 'Jonathan H. Wage';
                 $em->persist($user);
             }

• Doctrine 2 is faster than some raw PHP
  code? What?!?!?! HUH?
• It does a lot less, provides no features, no
  abstraction, etc.

• Why? The answer is transactions! Doctrine 2
  manages our transactions for us and
  efficiently executes all inserts in a single,
  short transaction. The raw PHP code
  executes 1 transaction for each insert.

                $cacheDriver = new DoctrineCommonCacheApcCache();
                $config->setResultCacheImpl($cacheDriver);


• Then you can configure each query to use
  the result cache or not.
             $query = $em->createQuery('select u from EntitiesUser u');
             $query->useResultCache(true, 3600, 'my_query_name');


• Executing this query the first time would
  populate a cache entry in $cacheDriver
  named my_query_name

             Class Table Inheritance
• Each class in a hierarchy is mapped to
  several tables: its own table and the tables
  of all parent classes.
• The table of a child class is linked to the
  table of a parent class through a foreign
  key constraint.
• A discriminator column is used in the
  topmost table of the hierarchy because this
  is the easiest way to achieve polymorphic
  queries.

Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

                       Batch Processing

  the transactional write-behind behavior of
  an EntityManager

                                        Bulk Delete
• Just like the bulk updates you can iterate
  over a query to avoid loading everything
  into memory all at once.

             $batchSize = 20;
             $i = 0;
             $q = $em->createQuery('select u from MyProjectModelUser u');

                 if (($i % $batchSize) == 0) {
                     $em->flush(); // Executes all deletions.
                     $em->clear(); // Detaches all objects from Doctrine!

NativeQuery + ResultSetMapping
• The NativeQuery class is used to execute
  raw SQL queries

• The ResultSetMapping class is used to
  define how to hydrate the results of that
  query




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

NativeQuery + ResultSetMapping
• Here is a simple example
      $rsm = new ResultSetMapping;
      $rsm->addEntityResult('DoctrineTestsModelsCMSCmsUser', 'u');
      $rsm->addFieldResult('u', 'id', 'id');
      $rsm->addFieldResult('u', 'name', 'name');

      $query = $this->_em->createNativeQuery(
          'SELECT id, name FROM cms_users WHERE username = ?',
          $rsm
      );
      $query->setParameter(1, 'romanb');

      $users = $query->getResult();




Doctrine 2     www.doctrine-project.org   www.sensiolabs.com
#sflive2010

NativeQuery + ResultSetMapping
• The result of $users would look like


             array(
                 [0] => User (Object)
             )




Doctrine 2   www.doctrine-project.org   www.sensiolabs.com
#sflive2010

NativeQuery + ResultSetMapping
• This means you will always be able to
  fallback to the power of raw SQL without
  losing the ability to hydrate the data to your
  entities

Doctrine 2 - Not The Same Old Php Orm

  • 1. #sflive2010 Doctrine 2 Not the same Old PHP ORM Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 2. #sflive2010 What is different in Doctrine 2? Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 3. #sflive2010 New code, new concepts, different workflow Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 4. #sflive2010 100% re-written codebase for PHP 5.3 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 5. #sflive2010 Are you scared? Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 6. #sflive2010 You shouldn’t be! It is a very exciting thing for PHP and change is a good thing! Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 7. #sflive2010 We learned lots building Doctrine 1 and we used that to help us build Doctrine 2 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 8. #sflive2010 Let me tell you why! Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 9. #sflive2010 Performance of Doctrine 1 To hydrate 5000 records in Doctrine 1 it takes roughly 4.3 seconds. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 10. #sflive2010 Performance of Doctrine 2 Under Doctrine 2, hydrating those same 5000 records only takes 1.4 seconds. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 11. #sflive2010 Performance of Doctrine 2 ...and with 10000 records it still only takes about 3.5 seconds. Twice the data and still faster than Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 12. #sflive2010 Performance of Doctrine 2 • More interesting than the numbers themselves is the percentage improvement over Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 13. #sflive2010 Why is it faster? • PHP 5.3 gives us a huge performance improvement when using a heavily OO framework like Doctrine • Better optimized hydration algorithm • New query and result caching implementations • All around more explicit and less magical code results in better and faster code. • Killed the magical aspect of Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 14. #sflive2010 Why kill the magic? • Eliminate the WTF? factor of Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 15. #sflive2010 The Doctrine 1 magical features are both a blessing and a curse Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 16. #sflive2010 Blessing and a Curse • Magic is great when it works • The magic you love is also the cause of all the pain you’ve felt with Doctrine 1 • When it doesn’t work it is hard to debug • Edge cases are hard to fix • Edge cases are hard to work around • Edge cases, edge cases, edge cases • Everything is okay until you try and go outside the box the magic provides • ...magic is slow Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 17. #sflive2010 How will we replace the magic? This new thing called OOP :) • Object Composition • Inheritance • Aggregation • Containment • Encapsulation • ...etc Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 18. #sflive2010 Will Doctrine 2 have behaviors? Yes and No Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 19. #sflive2010 The No • We won’t have any concept of “model behaviors” • Behaviors were a made up concept for Doctrine 1 to work with its extremely intrusive architecture. • It tries to do things that PHP does not allow and is the result of lots of problems in Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 20. #sflive2010 The Yes • Everything you can do in Doctrine 1 you can do in Doctrine 2, just in a different way. • “Behavior” like functionality will be bundled as extensions for Doctrine 2 and will just contain normal OO PHP code that wraps/ extends Doctrine code or is meant to be wrapped or extended by your entities. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 21. #sflive2010 What did we use to build Doctrine 2? Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 22. #sflive2010 Doctrine 2 Tool Belt • phpUnit 3.4.10 - Unit Testing • Phing - Packaging and Distribution • Symfony YAML Component • Sismo - Continuous Integration • Subversion - Source Control • Jira - Issue Tracking and Management • Trac - Subversion Timeline, Source Code Browser, Changeset Viewer Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 23. #sflive2010 Doctrine 2 Architecture • Entities • Lightweight persistent domain object • Regular PHP class • Does not extend any base Doctrine class • Cannot be final or contain final methods • Any two entities in a hierarchy of classes must not have a mapped property with the same name • Supports inheritance, polymorphic associations and polymorphic queries. • Both abstract and concrete classes can be entities • Entities may extend non-entity classes as well as entity classes, and non-entity classes may extend entity classes Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 24. #sflive2010 Doctrine 2 Architecture • Your entities in Doctrine 2 don’t require that you extend a base class like in Doctrine 1! No more imposing on your domain model! namespace Entities; class User { private $id; private $name; private $address; } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 25. #sflive2010 Doctrine 2 Architecture • The EntityManager • Central access point to the ORM functionality provided by Doctrine 2. API is used to manage the persistence of your objects and to query for persistent objects. • Employes transactional write behind strategy that delays the execution of SQL statements in order to execute them in the most efficient way • Execute at end of transaction so that all write locks are quickly releases • Internally an EntityManager uses a UnitOfWork to keep track of your objects Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 26. #sflive2010 Unit Testing • Tests are ran against multiple DBMS types. This is something that was not possible with the Doctrine 1 test suite. • ...Sqlite • ...MySQL • ...Oracle • ...PgSQL • ...more to come Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 27. #sflive2010 Unit Testing • 859 Test Cases • 2152 Assertions • Tests run in a few seconds compared to 30-40 seconds for Doctrine 1 • Much more granular and explicit unit tests • Easier to debug failed tests • Continuously integrated by Sismo :) Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 28. #sflive2010 Sismo – No, Sismo is not available yet!!!!!!!!! :) – Want it? Bug Fabien! Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 29. #sflive2010 Database Abstraction Layer • Separate standalone package and namespace (DoctrineDBAL). • Can be used standalone. • Much improved over Doctrine 1 in regards to the API for database introspection and schema management. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 30. #sflive2010 Database Abstraction Layer • Hopefully Doctrine 2 DBAL can be the defacto standard DBAL for PHP 5.3 in the future like MDB and MDB2 were in PEAR • Maybe we can make this happen for PEAR2? Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 31. #sflive2010 DBAL Data API • prepare($sql) - Prepare a given sql statement and return the DoctrineDBAL DriverStatement instance. • executeUpdate($sql, array $params) - Executes a prepared statement with the given sql and parameters and returns the affected rows count. • execute($sql, array $params) - Creates a prepared statement for the given sql and passes the parameters to the execute method, then returning the statement. • fetchAll($sql, array $params) - Execute the query and fetch all results into an array. • fetchArray($sql, array $params) - Numeric index retrieval of first result row of the given query. • fetchBoth($sql, array $params) - Both numeric and assoc column name retrieval of the first result row. • fetchColumn($sql, array $params, $colnum) - Retrieve only the given column of the first result row. • fetchRow($sql, array $params) - Retrieve assoc row of the first result row. • select($sql, $limit, $offset) - Modify the given query with a limit clause. • delete($tableName, array $identifier) - Delete all rows of a table matching the given identifier, where keys are column names. • insert($tableName, array $data) - Insert a row into the given table name using the Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 32. #sflive2010 DBAL Introspection API • listDatabases() • listFunctions() • listSequences() • listTableColumns($tableName) • listTableConstraints($tableName) • listTableDetails($tableName) • listTableForeignKeys($tableName) • listTableIndexes($tableName) • listTables() Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 33. #sflive2010 DBAL Schema Representation $schema = new DoctrineDBALSchemaSchema(); $myTable = $schema->createTable("my_table"); $myTable->createColumn("id", "integer", array("unsigned" => true)); $myTable->createColumn("username", "string", array("length" => 32)); $myTable->setPrimaryKey(array("id")); $myTable->addUniqueIndex(array("username")); $schema->createSequence("my_table_seq"); $myForeign = $schema->createTable("my_foreign"); $myForeign->createColumn("id", "integer"); $myForeign->createColumn("user_id", "integer"); $myForeign->addForeignKeyConstraint($myTable, array("user_id"), array("id"), array("onUpdate" => "CASCADE")); $queries = $schema->toSql($myPlatform); // get queries to create this schema. $dropSchema = $schema->toDropSql($myPlatform); // get queries to safely delete this schema. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 34. #sflive2010 Compare DBAL Schemas $comparator = new DoctrineDBALSchemaComparator(); $schemaDiff = $comparator->compare($fromSchema, $toSchema); // queries to get from one to another schema. $queries = $schemaDiff->toSql($myPlatform); $saveQueries = $schemaDiff->toSaveSql($myPlatform); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 35. #sflive2010 Schema Management • Extracted from ORM to DBAL • Schema comparisons replace the migrations diff tool of Doctrine 1 Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 36. #sflive2010 Doctrine 2 Annotations <?php namespace Entities; /** * @Entity @Table(name="users") */ class User { /** @Id @Column(type="integer") @GeneratedValue */ private $id; /** @Column(length=50) */ private $name; /** @OneToOne(targetEntity="Address") */ private $address; } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 37. #sflive2010 Things to Notice • Entities no longer require you to extend a base class! • Your domain model has absolutely no magic, is not imposed on by Doctrine and is defined by raw PHP objects and normal OO programming. • The performance improvement from this is significant. • Easier to understand what is happening due to less magic occurring. As Fabien says, “Kill the magic...” Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 38. #sflive2010 Doctrine 2 YAML EntitiesAddress: type: entity table: addresses id: id: type: integer generator: strategy: AUTO fields: street: type: string length: 255 oneToOne: user: targetEntity: User mappedBy: address Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 39. #sflive2010 Doctrine 2 XML <?xml version="1.0" encoding="UTF-8"?> <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd"> <entity name="EntitiesUser" table="users"> <id name="id" type="integer"> <generator strategy="AUTO"/> </id> <field name="name" type="string" length="50"/> <one-to-one field="address" target-entity="Address"> <join-column name="address_id" referenced-column-name="id"/> </one-to-one> </entity> </doctrine-mapping> Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 40. #sflive2010 Doctrine 2 Setup • PHP “use” all necessary namespaces and classes use DoctrineCommonClassLoader, DoctrineORMConfiguration, DoctrineORMEntityManager, DoctrineCommonCacheApcCache, EntitiesUser, EntitiesAddress; Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 41. #sflive2010 Doctrine 2 Setup • Require the Doctrine ClassLoader require '../../lib/Doctrine/Common/ClassLoader.php'; Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 42. #sflive2010 Doctrine 2 Setup • Setup autoloading for Doctrine classes • ...core classes • ...entity classes • ...proxy classes $doctrineClassLoader = new ClassLoader('Doctrine', '/path/to/doctrine'); $doctrineClassLoader->register(); $entitiesClassLoader = new ClassLoader('Entities', '/path/to/entities'); $entitiesClassLoader->register(); $proxiesClassLoader = new ClassLoader('Proxies', '/path/to/proxies'); $proxiesClassLoader->register(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 43. #sflive2010 Doctrine 2 Setup • Configure your Doctrine implementation // Set up caches $config = new Configuration; $cache = new ApcCache; $config->setMetadataCacheImpl($cache); $config->setQueryCacheImpl($cache); // Proxy configuration $config->setProxyDir('/path/to/proxies/Proxies'); $config->setProxyNamespace('Proxies'); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 44. #sflive2010 Doctrine 2 Setup • Create your database connection and entity manager // Database connection information $connectionOptions = array( 'driver' => 'pdo_sqlite', 'path' => 'database.sqlite' ); // Create EntityManager $em = EntityManager::create($connectionOptions, $config); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 45. #sflive2010 Doctrine 2 Setup • In production you would lazily load the EntityManager • Example: $em = function() { static $em; if (!$em) { $em = EntityManager::create($connectionOptions, $config); } return $em; } • In the real world I wouldn’t recommend that you use the above example • Symfony DI would take care of this for us Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 46. #sflive2010 Doctrine 2 Setup • Now you can start using your models and persisting entities $user = new User; $user->setName('Jonathan H. Wage'); $em->persist($user); $em->flush(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 47. #sflive2010 Insert Performance • Inserting 20 records with Doctrine for ($i = 0; $i < 20; ++$i) { $user = new User; $user->name = 'Jonathan H. Wage'; $em->persist($user); } $s = microtime(true); $em->flush(); $e = microtime(true); echo $e - $s; Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 48. #sflive2010 Insert Performance • Compare it to some raw PHP code $s = microtime(true); for ($i = 0; $i < 20; ++$i) { mysql_query("INSERT INTO users (name) VALUES ('Jonathan H. Wage')", $link); } $e = microtime(true); echo $e - $s; Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 49. #sflive2010 Insert Performance • The results might be surprising to you. Which do you think is faster? Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 50. #sflive2010 Insert Performance Doctrine 2 0.0094 seconds mysql_query 0.0165 seconds Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 51. #sflive2010 Insert Performance • Doctrine 2 is faster than some raw PHP code? What?!?!?! HUH? • It does a lot less, provides no features, no abstraction, etc. • Why? The answer is transactions! Doctrine 2 manages our transactions for us and efficiently executes all inserts in a single, short transaction. The raw PHP code executes 1 transaction for each insert. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 52. #sflive2010 Insert Performance • Here is the same raw PHP code re-visited with proper transaction usage. $s = microtime(true); mysql_query('START TRANSACTION', $link); for ($i = 0; $i < 20; ++$i) { mysql_query("INSERT INTO users (name) VALUES ('Jonathan H. Wage')", $link); } mysql_query('COMMIT', $link); $e = microtime(true); echo $e - $s; Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 53. #sflive2010 Insert Performance • Not trying to say Doctrine 2 is faster than raw PHP code • Demonstrating that simple developer oversights and mis-use can cause the greatest performance problems Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 54. #sflive2010 Insert Performance • This time around it only takes 0.0028 seconds compared to the previous 0.0165 seconds. That’s a pretty huge improvement. • You can read more about this on the Doctrine Blog http://www.doctrine-project.org/blog/transactions-and-performance Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 55. #sflive2010 Doctrine Query Language • DQL parser completely re-written from scratch • ...DQL is parsed by a top down recursive descent parser that constructs an AST (abstract syntax tree). • ...The AST is used to generate the SQL to execute for your DBMS http://www.doctrine-project.org/documentation/manual/2_0/en/dql-doctrine-query-language Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 56. #sflive2010 Doctrine Query Language • Here is an example DQL query $q = $em->createQuery('select u from MyProjectModelUser u'); $users = $q->execute(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 57. #sflive2010 Doctrine Query Language • Here is that same DQL query using the QueryBuilder API $qb = $em->createQueryBuilder() ->select('u') ->from('MyProjectModelUser', 'u'); $q = $qb->getQuery(); $users = $q->execute(); http://www.doctrine-project.org/documentation/manual/2_0/en/query-builder Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 58. #sflive2010 Doctrine Query Builder • QueryBuilder API is the same as Doctrine_Query API in Doctrine 1 • Query building and query execution are separated • True builder pattern used • QueryBuilder is used to build instances of Query • You don’t execute a QueryBuilder, you get the built Query instance from the QueryBuilder and execute it Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 59. #sflive2010 Cache Drivers • Public interface of all cache drivers • fetch($id) - Fetches an entry from the cache. • contains($id) - Test if an entry exists in the cache. • save($id, $data, $lifeTime = false) - Puts data into the cache. • delete($id) - Deletes a cache entry. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 60. #sflive2010 Cache Drivers • Wrap existing Symfony, ZF, etc. cache driver instances with the Doctrine interface Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 61. #sflive2010 Cache Drivers • deleteByRegex($regex) - Deletes cache entries where the key matches a regular expression • deleteByPrefix($prefix) - Deletes cache entries where the key matches a prefix. • deleteBySuffix($suffix) - Deletes cache entries where the key matches a suffix. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 62. #sflive2010 Cache Drivers • Each driver extends the AbstractCache class which defines a few abstract protected methods that each of the drivers must implement to do the actual work • _doFetch($id) • _doContains($id) • _doSave($id, $data, $lifeTime = false) • _doDelete($id) Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 63. #sflive2010 APC Cache Driver • To use the APC cache driver you must have it compiled and enabled in your php.ini $cacheDriver = new DoctrineCommonCacheApcCache(); $cacheDriver->save('cache_id', 'my_data'); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 64. #sflive2010 Memcache Cache Driver • To use the memcache cache driver you must have it compiled and enabled in your php.ini $memcache = new Memcache(); $memcache->connect('memcache_host', 11211); $cacheDriver = new DoctrineCommonCacheMemcacheCache(); $cacheDriver->setMemcache($memcache); $cacheDriver->save('cache_id', 'my_data'); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 65. #sflive2010 Xcache Cache Driver • To use the xcache cache driver you must have it compiled and enabled in your php.ini $cacheDriver = new DoctrineCommonCacheXcacheCache(); $cacheDriver->save('cache_id', 'my_data'); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 66. #sflive2010 Result Cache • First you need to configure the result cache $cacheDriver = new DoctrineCommonCacheApcCache(); $config->setResultCacheImpl($cacheDriver); • Then you can configure each query to use the result cache or not. $query = $em->createQuery('select u from EntitiesUser u'); $query->useResultCache(true, 3600, 'my_query_name'); • Executing this query the first time would populate a cache entry in $cacheDriver named my_query_name Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 67. #sflive2010 Result Cache • Now you can clear the cache for that query by using the delete() method of the cache driver $cacheDriver->delete('my_query_name'); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 68. #sflive2010 Command Line Interface • Re-written command line interface to help developing with Doctrine Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 69. #sflive2010 dbal:run-sql • Execute a manually written SQL statement • Execute multiple SQL statements from a file Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 70. #sflive2010 orm:clear-cache • Clear all query, result and metadata cache • Clear only query cache • Clear only result cache • Clear only metadata cache • Clear a single queries result cache • Clear keys that match regular expression • Clear keys that match a prefix • Clear keys that match a suffix Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 71. #sflive2010 So now when you have a problem in Doctrine, like Symfony, you can try clearing the cache first :) Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 72. #sflive2010 orm:convert-mapping • Convert metadata information between formats • Convert metadata information from an existing database to any supported format (yml, xml, annotations, etc.) • Convert mapping information from xml to yml or vice versa • Generate PHP classes from mapping information with mutators and accessors Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 73. #sflive2010 orm:ensure-production-settings • Verify that Doctrine is properly configured for a production environment. • Throws an exception when environment does not meet the production requirements Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 74. #sflive2010 orm:generate-proxies • Generate the proxy classes for entity classes. • A proxy object is an object that is put in place or used instead of the "real" object. A proxy object can add behavior to the object being proxied without that object being aware of it. In Doctrine 2, proxy objects are used to realize several features but mainly for transparent lazy-loading. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 75. #sflive2010 orm:run-dql • Execute a DQL query from the command line Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 76. #sflive2010 orm:schema-tool • Drop, create and update your database schema. • --create option creates the initial tables for your schema • --drop option drops the the tables for your schema • --update option compares your local schema information to the database and updates it accordingly Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 77. #sflive2010 Inheritance • Doctrine 2 fully supports inheritance. We allow the following types of inheritance: • ...Mapped Superclasses • ...Single Table Inheritance • ...Class Table Inheritance Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 78. #sflive2010 Mapped Superclasses /** @MappedSuperclass */ class MappedSuperclassBase { /** @Column(type="integer") */ private $mapped1; /** @Column(type="string") */ private $mapped2; /** * @OneToOne(targetEntity="MappedSuperclassRelated1") * @JoinColumn(name="related1_id", referencedColumnName="id") */ private $mappedRelated1; // ... more fields and methods } /** @Entity */ class EntitySubClass extends MappedSuperclassBase { /** @Id @Column(type="integer") */ private $id; /** @Column(type="string") */ private $name; // ... more fields and methods } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 79. #sflive2010 Mapped Superclasses CREATE TABLE EntitySubClass (mapped1 INTEGER NOT NULL, mapped2 TEXT NOT NULL, id INTEGER NOT NULL, name TEXT NOT NULL, related1_id INTEGER DEFAULT NULL, PRIMARY KEY(id)) http://www.doctrine-project.org/documentation/manual/2_0/en/inheritance-mapping#mapped-superclasses Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 80. #sflive2010 Single Table Inheritance /** * @Entity * @InheritanceType("SINGLE_TABLE") * @DiscriminatorColumn(name="discr", type="string") * @DiscriminatorMap({"person" = "Person", "employee" = "Employee"}) */ class Person { // ... } /** * @Entity */ class Employee extends Person { // ... } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 81. #sflive2010 Single Table Inheritance • All entities share one table. • To distinguish which row represents which type in the hierarchy a so-called discriminator column is used. http://www.doctrine-project.org/documentation/manual/2_0/en/inheritance-mapping#single-table-inheritance Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 82. #sflive2010 Class Table Inheritance namespace MyProjectModel; /** * @Entity * @InheritanceType("JOINED") * @DiscriminatorColumn(name="discr", type="string") * @DiscriminatorMap({"person" = "Person", "employee" = "Employee"}) */ class Person { // ... } /** @Entity */ class Employee extends Person { // ... } http://www.doctrine-project.org/documentation/manual/2_0/en/inheritance-mapping#single-table-inheritance Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 83. #sflive2010 Class Table Inheritance • Each class in a hierarchy is mapped to several tables: its own table and the tables of all parent classes. • The table of a child class is linked to the table of a parent class through a foreign key constraint. • A discriminator column is used in the topmost table of the hierarchy because this is the easiest way to achieve polymorphic queries. Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 84. #sflive2010 Batch Processing • Doctrine 2 offers the ability to do some batch processing by taking advantage of the transactional write-behind behavior of an EntityManager Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 85. #sflive2010 Bulk Inserts • Insert 10000 objects with a batch size of 20 $batchSize = 20; for ($i = 1; $i <= 10000; ++$i) { $user = new CmsUser; $user->setStatus('user'); $user->setUsername('user' . $i); $user->setName('Mr.Smith-' . $i); $em->persist($user); if ($i % $batchSize == 0) { $em->flush(); $em->clear(); // Detaches all objects from Doctrine! } } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 86. #sflive2010 Bulk Update • Bulk update with DQL $q = $em->createQuery('update MyProjectModelManager m set m.salary = m.salary * 0.9'); $numUpdated = $q->execute(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 87. #sflive2010 Bulk Update • Bulk update by iterating over the results using the Query::iterate() method to avoid loading everything into memory at once $batchSize = 20; $i = 0; $q = $em->createQuery('select u from MyProjectModelUser u'); $iterableResult = $q->iterate(); foreach($iterableResult AS $row) { $user = $row[0]; $user->increaseCredit(); $user->calculateNewBonuses(); if (($i % $batchSize) == 0) { $em->flush(); // Executes all updates. $em->clear(); // Detaches all objects from Doctrine! } ++$i; } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 88. #sflive2010 Bulk Delete • Bulk delete with DQL $q = $em->createQuery('delete from MyProjectModelManager m where m.salary > 100000'); $numDeleted = $q->execute(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 89. #sflive2010 Bulk Delete • Just like the bulk updates you can iterate over a query to avoid loading everything into memory all at once. $batchSize = 20; $i = 0; $q = $em->createQuery('select u from MyProjectModelUser u'); $iterableResult = $q->iterate(); while (($row = $iterableResult->next()) !== false) { $em->remove($row[0]); if (($i % $batchSize) == 0) { $em->flush(); // Executes all deletions. $em->clear(); // Detaches all objects from Doctrine! } ++$i; } Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 90. #sflive2010 NativeQuery + ResultSetMapping • The NativeQuery class is used to execute raw SQL queries • The ResultSetMapping class is used to define how to hydrate the results of that query Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 91. #sflive2010 NativeQuery + ResultSetMapping • Here is a simple example $rsm = new ResultSetMapping; $rsm->addEntityResult('DoctrineTestsModelsCMSCmsUser', 'u'); $rsm->addFieldResult('u', 'id', 'id'); $rsm->addFieldResult('u', 'name', 'name'); $query = $this->_em->createNativeQuery( 'SELECT id, name FROM cms_users WHERE username = ?', $rsm ); $query->setParameter(1, 'romanb'); $users = $query->getResult(); Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 92. #sflive2010 NativeQuery + ResultSetMapping • The result of $users would look like array( [0] => User (Object) ) Doctrine 2 www.doctrine-project.org www.sensiolabs.com
  • 93. #sflive2010 NativeQuery + ResultSetMapping • This means you will always be able to fallback to the power of raw SQL without losing the ability to hydrate the data to your entities Doctrine 2 www.doctrine-project.org www.sensiolabs.com
