Agenda - Introduction to MongoDB - PHP and MongoDB - PHP Libraries - Symfony2 and MongoDBFriday, May 18, 2012

What is MongoDB? Who is 10Gen?Friday, May 18, 2012

Mongo Mongo as in "humongous". Used to describe something extremely large or important.Friday, May 18, 2012

MongoDB is a scalable, high-performance, open source NoSQL database. - Document Oriented DB - Written in C++ - Available for *nux (Linux, Solaris, etc), Windows and OS X - Lots of Drivers (PHP, Java, Python, Ruby...)Friday, May 18, 2012

Features - Flexible JSON-style documents - Full Indexing - Complex Queries / Map Reduce - Aggregation Framework (coming soon) - GridFS (store ﬁles natively) - Multiple Replication Options - Sharding - Simple Installation / Zero ConﬁgFriday, May 18, 2012

Document Oriented Coming from SQL? Database => Database Table => Collection Row => DocumentFriday, May 18, 2012

JSON-style documents { name: { ﬁrst: John, last: Doe }, title: Engineer, age: 40 }Friday, May 18, 2012

No Schema or ﬁxed tables { name: { ﬁrst: Foo, last: Bar }, title: Student, school: Harvard }Friday, May 18, 2012

Embedded documents { "_id" : ObjectId("4ccba15ef597e9352e060000") "srcFilename" : "/etc/apache2/sites-enabled/example1.com", "vhostDirective" : { "directives" : [ { "name" : "CustomLog", "value" : "logs/example1.com-access_log combined" }, { "name" : "DocumentRoot", "value" : "/var/www/vhosts/example1.com/httpdocs" }, { "name" : "ServerName", "value" : "example1.com" } ] } }Friday, May 18, 2012

Document Referencing { "_id" : ObjectId("4cc4a5c3f597e9db6e010109"), "billingId" : NumberLong(650), "created" : ISODate("2010-10-24T21:31:47Z"), "servers" : [ { "$ref" : "server", "$id" : ObjectId("4cc4a5c4f597e9db6e050201") } ], "users" : [ { "$ref" : "user", "$id" : ObjectId("4cc4a5c4f597e9db6e980201") }, { "$ref" : "user", "$id" : ObjectId("4cc4a5c4f597e9db6e9c0201") } ] }Friday, May 18, 2012

Full Indexing db.coll.ensureIndex({name.last: 1}) db.coll.ensureIndex({name.ﬁrst: 1, name.last: 1}) db.coll.ensureIndex({age: 0})Friday, May 18, 2012

Querying db.coll.find({name: John}) db.coll.find({keywords: storage}) db.coll.find({keywords: {$in: [storage, DBMS]}}Friday, May 18, 2012

GridFS - Files are divided in chunks and stored over multiple documents - Transparent APIFriday, May 18, 2012

Usage <?php // connect $m = new Mongo(); // select a database $db = $m->comedy; // select a collection (analogous to a relational databases table) $collection = $db->cartoons; // add a record $obj = array ( "title" => "Calvin and Hobbes", "author" => "Bill Watterson" ); $collection->insert($obj); // add another record, with a different "shape" $obj = array( "title" => "XKCD", "online" => true ); $collection->insert($obj); // find everything in the collection $cursor = $collection->find(); // iterate through the results foreach ($cursor as $obj) { echo $obj["title"] . "n"; } ?>Friday, May 18, 2012

Storing Files <?php // save a file $id = $grid->storeFile("game.tgz"); $game = $grid->findOne(); // add a downloads counter $game->file[downloads] = 0; $grid->save($game->file); // increment the counter $grid->update(array("_id" => $id), array($inc => array ("downloads" => 1))); ?>Friday, May 18, 2012

SQL to Mongo Queries SQL to Mongo Mapping Chart This is a PHP-specific version of the » SQL to Mongo mapping chart in the main docs. SQL Statement Mongo Query Language Statement CREATE TABLE USERS (a Number, b Number) Implicit or use MongoDB::createCollection(). INSERT INTO USERS VALUES(1,1) $db->users->insert(array("a" => 1, "b" => 1)); SELECT a,b FROM users $db->users->find(array(), array("a" => 1, "b" => 1)); SELECT * FROM users WHERE age=33 $db->users->find(array("age" => 33)); SELECT a,b FROM users WHERE age=33 $db->users->find(array("age" => 33), array("a" => 1, "b" => 1)); SELECT a,b FROM users WHERE age=33 ORDER BY name $db->users->find(array("age" => 33), array("a" => 1, "b" => 1))->sort(array("name" => 1)); SELECT * FROM users WHERE age>33 $db->users->find(array("age" => array($gt => 33))); SELECT * FROM users WHERE age<33 $db->users->find(array("age" => array($lt => 33))); SELECT * FROM users WHERE name LIKE "%Joe%" $db->users->find(array("name" => new MongoRegex("/Joe/"))); SELECT * FROM users WHERE name LIKE "Joe%" $db->users->find(array("name" => new MongoRegex("/^Joe/"))); SELECT * FROM users WHERE age>33 AND age<=40 $db->users->find(array("age" => array($gt => 33, $lte => 40))); SELECT * FROM users ORDER BY name DESC http://php.net/manual/en/mongo.sqltomongo.phpFriday, May 18, 2012

DoctrineMongoDBBundle Deﬁning DocumentsFriday, May 18, 2012

DoctrineMongoDBBundle Deﬁning Documents // src/Acme/StoreBundle/Document/Product.php namespace AcmeStoreBundleDocument; use DoctrineODMMongoDBMappingAnnotations as MongoDB; /** * @MongoDBDocument(collection="product") */ class Product { /** * @MongoDBId */ protected $id; /** * @MongoDBString @MongoDBIndex(unique=true, order="asc") */ protected $name;Friday, May 18, 2012

DoctrineMongoDBBundle Using Documents // src/Acme/StoreBundle/Controller/DefaultController.php use AcmeStoreBundleDocumentProduct; use SymfonyComponentHttpFoundationResponse; // ... public function createAction() { $product = new Product(); $product->setName(A Foo Bar); $product->setPrice(19.99); $dm = $this->get(doctrine.odm.mongodb.document_manager); $dm->persist($product); $dm->flush(); return new Response(Created product id .$product->getId()); }Friday, May 18, 2012

Forms Since Documents are Plain PHP Objects integrating it with Symfony Forms is straightforward. public function createAction() { $dm = $this->get (doctrine.odm.mongodb.default_document_manager); $form = $this->createForm(new RegistrationType(), new Registration()); $form->bindRequest($this->getRequest()); if ($form->isValid()) { $registration = $form->getData(); $dm->persist($registration->getUser()); $dm->flush(); return $this->redirect(...); } http://symfony.com/doc/master/bundles/DoctrineMongoDBBundle/form.htmlFriday, May 18, 2012

Commands Symfony2 Commands doctrine doctrine:mongodb:cache:clear-metadata Clear all metadata cache for a document manager. doctrine:mongodb:fixtures:load Load data fixtures to your database. doctrine:mongodb:generate:documents Generate document classes and method stubs from your mapping information. doctrine:mongodb:generate:hydrators Generates hydrator classes for document classes. doctrine:mongodb:generate:proxies Generates proxy classes for document classes. doctrine:mongodb:generate:repositories Generate repository classes from your mapping information. doctrine:mongodb:mapping:info Show basic information about all mapped documents. doctrine:mongodb:query Query mongodb and inspect the outputted results from your document classes. doctrine:mongodb:schema:create Allows you to create databases, collections and indexes for your documents doctrine:mongodb:schema:drop Allows you to drop databases, collections and indexes for your documentsFriday, May 18, 2012
