  • 1. MongoSF - PHP Development With MongoDB Presented By: Fitz Agard - LightCube Solutions LLC April 30, 2010
  • 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. 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. 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. 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. 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. 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, $metaData);
  • 8. Mongo and PHP in a Nutshell (Using GridFS) public function remove($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. Let’s develop a simple student information capture system with mongoDB and PHP!
  • 10. Typical Development Cycle Design Test Develop
  • 11. Typical Design Design (The Schema) Test Develop
  • 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. 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. 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. 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. 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. 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. 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. 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. Design and Development In Summary Our Classes/Methods/Views made the schema NoSQL NoORM Arrays! Arrays! Arrays!
  • 21. Design Let’s Test Test Develop What does MongoDB have to do with testing?
  • 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. 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. Wait, there is MORE!
  • 25. Cursors MongoDates Indexes MapReduce ...Just to name a few... Sharding Exceptions MongoBinData MongoCode MongoRegex

  • 27. { “type”: “Conclusion”, “date”: new Date('04-30-2010'), “comments”: [“Thank You”,”Have Fun Developing”], “location”: “San Francisco”, “speaker”: “Fitz H. Agard”, “contact”: “fhagard@lightcube.us” }
