  • PHP Development with MongoDB (Fitz Agard)

    1. 1. MongoSF - PHP Development With MongoDB Presented By: Fitz Agard - LightCube Solutions LLC April 30, 2010
    2. 2. Introductions - Who is this guy? { “name”: “Fitz Agard”, “description”: [“Developer”,”Consultant”,”Data Junkie”, “Educator”, “Engineer”], “location”: “New York”, “companies”:[ {“name”: “LightCube Solutions”, “url”: “www.lightcubesolutions.com”} ], “urls”:[ {“name”: “LinkedIn”, “url”: “http://www.linkedin.com/in/fitzagard”}, {“name”: “Twitter”, “url”: “http://www.twitter.com/fitzhagard”} ], “email”: “fhagard@lightcube.us” } (If the above formatting confused you please see - http://json.org/)
    3. 3. Why PHP Developers Should Use MongoDB? PHP Reasons Database Reasons • Enhanced Development Cycle - Itʼs no longer • Document-oriented storage - JSON-style documents with dynamic necessary to go back and forth between the Database schemas offer simplicity and power. Schema and Object. • Full Index Support - Index on any attribute. • Easy Ramp-Up - Queries are just an array away. • Replication & High Availability - Mirror across LANs and WANs. • No Need For ORM - No Schema! • Auto-Sharding - Scale horizontally without compromising functionality. • DBA? What DBA? • Querying - Rich, document-based queries. • Arrays, Array, Arrays! • Fast In-Place Updates - Atomic modifiers for contention-free performance. • Map/Reduce - Flexible aggregation and data processing. • GridFS - Store files of any size.
    4. 4. Mongo and PHP in a Nutshell http://us.php.net/manual/en/book.mongo.php Common Methods Conditional Operators • find() • $ne • findOne() • $in • save() • $nin • remove() • $mod • update() • $all • group() • $size • limit() • $exists • skip() • $type • ensureIndex() • $gt • count() • $lt • ...And More • $lte • $gte
    5. 5. Mongo and PHP in a Nutshell (Connectivity) http://us2.php.net/manual/en/mongo.connecting.php function __construct() { global $dbname, $dbuser, $dbpass; $this->dbname = $dbname; $this->dbuser = $dbuser; $this->dbpass = $dbpass; // Make the initial connection try { $this->_link = new Mongo(); // Select the DB $this->db = $this->_link->selectDB($this->dbname); // Authenticate $result = $this->db->authenticate($this->dbuser, $this->dbpass); if ($result['ok'] == 0) { // Authentication failed. $this->error = ($result['errmsg'] == 'auth fails') ? 'Database Authentication Failure' : $result['errmsg']; $this->_connected = false; } else { $this->_connected = true; } } catch (Exception $e) { $this->error = (empty($this->error)) ? 'Database Connection Error' : $this->error; } }
    6. 6. Mongo and PHP in a Nutshell (Simple Queries) http://us2.php.net/manual/en/mongo.queries.php /* * SELECT * FROM students * WHERE isSlacker = true * AND postalCode IN (10466,10407,10704) * AND gradYear BETWEEN (2010 AND 2014) * ORDER BY lastName DESC */ $collection = $this->db->students; $collection->ensureIndex(array('isSlacker'=>1, 'postalCode'=>1, 'lastName'=>1, 'gradYear'=>-1)); $conditions = array('postalCode'=>array('$in'=>array(10466,10407,10704)), 'isSlacker'=>true, 'gradYear'=>array('$gt'=>2010, '$lt'=>2014)); $results = $collection->find($conditions)->sort(array('lastName'=>1)); $collection = $this->db->grades; //SELECT count(*) FROM grades $total = $collection->count(); //SELECT count(*) FROM grades WHERE grade = 90 $smartyPants = $collection->find(array("grade"=>90))->count();
    7. 7. Mongo and PHP in a Nutshell (Using GridFS) http://us2.php.net/manual/en/class.mongogridfs.php $m = new Mongo(); //select Mongo Database $db = $m->selectDB("studentsystem"); //use GridFS class for handling files $grid = $db->getGridFS(); //Optional - capture the name of the uploaded file $name = $_FILES['Filedata']['name']; //load file into MongoDB and get back _id $id = $grid->storeUpload('Filedata',$name); //set a mongodate $date = new MongoDate(); //Use $set to add metadata to a file $metaData = array('$set' => array("comment"=>"This looks like a MongoDB Student", "date"=>$date)); //Just setting up search criteria $criteria = array('_id' => $id); //Update the document with the new info $db->grid->update($criteria, $metaData);
    8. 8. Mongo and PHP in a Nutshell (Using GridFS) public function remove($criteria) { //Get the GridFS Object $grid = $this->db->getGridFS(); //Setup some criteria to search for file $id = new MongoID($criteria['_id']); //Remove file $grid->remove(array('_id'=>$id), true); //Get lastError array $errorArray = $db->lastError(); if ($errorArray['ok'] == 1 ) { $retval = true; }else{ //Send back the error message $retval = $errorArray['err']; } return $retval; }
    9. 9. Let’s develop a simple student information capture system with mongoDB and PHP!
    10. 10. Typical Development Cycle Design Test Develop
    11. 11. Typical Design Design (The Schema) Test Develop
    12. 12. Our Design Design (The Mongo Model) Test Develop db.students db.teachers firstName: firstName: lastName: lastName: address: isCrazy: address: city: state: postalCode: db.courses grades: name: grade: isImpossible: course: teacher: createdDate: modifiedDate: comment: schedule: course: sysInfo: Whiteboards aren’t this neat but they are just as good! username: password: isSlacker: gradYear:
    13. 13. Some Wireframes Design (The View) Test Develop Select Course: - Select One - * Required User Name: * Required Select Student: - Select One - * Required Password: ***************** * Required Grade: First Name: * Required Submit Last Name: * Required Address: * Required City, State, Postal Code: City - State - Postal Code * Required Click if this student is a slacker Imagine the code for this Graduation Date: mm/dd/yyyy Submit
    14. 14. Design We’re Developing Test Develop public function studentUpdate() { $mongo_id = new MongoID($_POST['_id']); $data = $this->cleanupData($_POST); $this->col->update(array("_id" => $mongo_id), array('$push' => $data)); return; } $_POST = '4b7c29908ead0e2e1d000000'; $data = array('firstName'=>'Fitz', 'lastName'=>'Agard', 'address'=>array( 'address'=>'123 Data Lane', 'state'=>'New York', Letʼs assume cleanupData only removes 'postalCode'=>10704 unnecessary POST elements like the _id ), 'sysInfo'=>array( 'username'=>'fhagard', 'password'=>sha1('MongoW00t') ), 'isSlacker'=>true, 'gradYear'=>2003 );
    15. 15. Design We’re Developing Test Develop public function studentUpdate() { $mongo_id = new MongoID($_POST['_id']); $data = $this->cleanupData($_POST); $this->col->update(array("_id" => $mongo_id), array('$push' => $data)); return; } $_POST = '4b7c29908ead0e2e1d000000'; $data = array('grades'=>array( 'grade'=>'3.8', 'course'=>'4bd0dd44cc93740f3e00251c', 'createDate'=>new MongoDate())); Donʼt forget that cleanupData only removes unnecessary POST elements like the _id
    16. 16. Design Test Develop Problem: The client called and asked why we forgot to collect “student infractions” in our design. oops! “oops” - used typically to express mild apology, surprise, or dismay.
    17. 17. Development back to Design Design (“oops” is easily fixed) Test Develop db.students firstName: lastName: address: address: city: state: postalCode: infractions: grades: desc: grade: date: course: createdDate: modifiedDate: comment: schedule: course: sysInfo: username: password: Back to the whiteboard (or - napkin, omnigraffle, visio, etc) isSlacker: gradYear:
    18. 18. Another Wireframe Design (The View - Again) Test Develop Infraction View Search for Student Input Search Last Name First Name Graduating Year Course Imagine the Editor Controls A ab new code for Format Font Size B i u 1 2 this. 3 Textarea enter text Date Selector __ / __ / ____ Select a date range Submit
    19. 19. Design right back to Development Design (The Fix! Do you see it?) Test Develop public function studentUpdate() { $mongo_id = new MongoID($_POST['_id']); $data = $this->cleanupData($_POST); $this->col->update(array("_id" => $mongo_id), array('$push' => $data)); return; } $_POST['_id'] = '4b7c29908ead0e2e1d000000'; $data = array('infractions'=> array('desc'=>'Caught Sharding', 'date'=> new MongoDate())); Answer: The only thing that changed was the view in the last slide. This code is the same!
    20. 20. Design and Development In Summary Our Classes/Methods/Views made the schema NoSQL NoORM Arrays! Arrays! Arrays!
    21. 21. Design Let’s Test Test Develop What does MongoDB have to do with testing?
    22. 22. Design Let’s Test Test Develop Isn’t it a good idea to run unit tests often? Where do you store the results?
    23. 23. Idea: PHPUnit to Mongo Design (Test Logging) Test Develop Test logs can go in Mongo Clipping from: http://www.phpunit.de/manual/current/en/logging.html#logging.json
    24. 24. Wait, there is MORE!
