5. What is it? PHP Web Framework Lightweight (half-stack) Open Source

6. Who’s behind it? Eric Barnes @ericlbarnes Taylor Otwell @taylorotwell Ian

7. I already use X. Why should I use Laravel?

8. Why use it? Built on PHP 5.3 Sinatra-style Routing Bundles

   http://bundles.laravel.com/ Artisan CLI Tool Wave your PHP flag proudly that’s right, I use PHP sucka Expressive Syntax Eloquent ORM Well Documented

9. Why use it? Expressive Syntax Utilizes the latest PHP features

   Route::get('user/(:num)', function($id) { $user = User::find($id); return View::make('home')->with('user', $user); }); <?php namespace Eloquent; use Laravel\Database as DB; abstract class Model {

10. Why use it? Bundles http://bundles.laravel.com/ $ php artisan bundle:install twilio

    Artisan CLI Tool $ php artisan bundle:install twilio Well Documented http://laravel.com/docs

11. Why use it? Sinatra-style Routing Eloquent ORM Route::get('/', function() {

    //do neat shit }); $user = new User; $user->id = 1; $user->save(); $user = User::find(1);

12. Let’s do some comparisons

13. Comparison MVC Design Sparks Lightweight Fast Excellent Docs Compatibility Technical

    Debt

14. Comparison HMVC Design Lightweight-ish Fast Horrible Docs API Changes Frequently

15. Comparison MVC Design Heavy Large Learning Curve Slow Decent Docs

    Modular Backed by ZEND

16. Comparison HMVC Design Lightweight Fast Excellent Docs Packages? Learned from

    other frameworks

17. MV[CR] Design Bundles Lightweight Fast Excellent Docs Threw out previous

    framework ideas and started over Comparison

18. OK, I’ll try it. How do I get started?

19. Download https://github.com/laravel/laravel $ git clone https://github.com/laravel/laravel.git .

20. Bundles http://bundles.laravel.com/ $ php artisan bundle:install twilio $ php artisan

    bundle:upgrade twilio

21. Structure MV[CR] Design Model View Controller || Route || Both

    Bundles Self contained modules Has it’s own config, models, routes, views, etc...

22. Structure application - config - controllers - models - views

    - routes.php - bundles.php - etc... laravel public - css - img - js - etc...

23. Create Route Create routes at: application/routes.php include() additional route definitions

    if needed

24. Create Route application/routes.php Route::get('/', function() { echo ‘Boom!’; });

25. Unit Test Runs all tests located at: application/tests/*.test.php $ php

    artisan test

26. Unit Test application/tests/routes.test.php Test that biotch! class TestRoutes extends PHPUnit_Framework_TestCase

    { public function testBase() { $response = Route::forward('GET', '/'); $this->assertEquals('Boom!', $response); }

27. Unit Test $ php artisan test Run it! PHPUnit 3.6.10

    by Sebastian Bergmann. Configuration read from ...www/laravel/develop/phpunit.xml Time: 0 seconds, Memory: 6.25Mb OK (1 test, 1 assertion) Output

28. What about an API? Routes to the rescue!

29. API application/routes.php Route::get('api/user/(:num)', function($id) { return json_encode(array( ‘users‘ => User::find($id),

    ‘success‘ => true ); });

30. API application/routes.php Route::put('api/user', function() { $user = User::create(array( 'email' =>

    Input::get(‘email’) )); return json_encode(array( ‘user_id‘ => $user->id, ‘success‘ => true ); });

31. Controllers OK, routes are cool and all, but what if

    I want to use controllers?

32. Controllers application/routes.php Route::controller(Controller::detect()); This will give you “CodeIgniter style” controller

    routing.

33. Shit just got real

34. Routes

35. Routes What methods are available: Route::get(); Route::post(); Route::put(); Route::delete(); Route::any();

    //all of the above

36. Routes Register multiple verbs for a single route: Router::register(array('GET', 'POST'),

    $uri, function(){ //this will run for both get and post });

37. Route Filters Run before or after a given route. Register

    a filter: Route::filter('auth', function() { if (Auth::guest()) return Redirect::to('login'); });

38. Route Filters Assign a filter to a route: Route::get('api/user', array('before'

    => 'auth', function() { ... }));

39. Route Filters Pattern matching adds a ton of flexibility: Route::filter('pattern:

    api/*', 'auth');

40. Models

41. Models Fluent Query Builder Eloquent ORM Schema Builder Migrations

42. Fluent Query Builder Similar to CI DB Class Simple and

    Easy to Understand Used extensively by Eloquent ORM

43. Fluent Query Builder $user = DB::table('users')->where_email('[email protected]') ->first(); Query Row by

    Email $id = DB::table('users')->insert_get_id(array( 'email' => '[email protected]' )); Insert & Get ID

44. Eloquent ORM Simple Expressive Efficient

45. Eloquent ORM class User extends Eloquent { } Define an

    Eloquent model class Post extends Eloquent { }

46. Eloquent ORM $user = User::where_email(‘[email protected]’)->first(); Simple query $user = Post::where('views',

    '>', 100)->get(); Slightly more advanced query

47. Eloquent ORM Relationships class Post extends Eloquent { public function

    user() { return $this->belongs_to('User'); } } Post::find(1)->user->email; Retrieve Post Creator Email

48. Eloquent ORM Normal Usage $posts = Post::all(); foreach ($posts as

    $post) { echo $post->user->email; } 100 posts = 101 queries SELECT * FROM "posts" foreach result { SELECT * FROM "users" WHERE "id" = 1 }

49. WTF!? ORMs Suck!

50. Eloquent ORM Eager Loading $posts = Post::with(‘user’)->get(); foreach ($posts as

    $post) { echo $post->user->email; } 100 posts = 2 queries SELECT * FROM "posts" SELECT * FROM "users" WHERE "id" IN (1, 2, 3, 4, 5, ...) Eager Loading FTW!

51. Eloquent ORM Normal Usage $posts = Post::all(); foreach ($posts as

    $post) { echo $post->user->email; } 100 posts = 101 queries SELECT * FROM "posts" foreach result { SELECT * FROM "users" WHERE "id" = 1 } Eager Loading $posts = Post::with(‘user’)->get(); foreach ($posts as $post) { echo $post->user->email; } 100 posts = 2 queries SELECT * FROM "posts" SELECT * FROM "users" WHERE "id" IN (1, 2, 3, 4, 5, ...)

52. Views

53. Views Route::get('/', function() { return View::make('home.index'); //views/home/index.php }); Returning a

    view from a route

54. Views Route::get('/', function() { return View::make('home.index')->with('email', '[email protected]'); Sending data to

    a view with magic methods Route::get('/', function() { $view = View::make('home.index'); $view->email = ‘[email protected]’; return $view; Sending data to a view

55. That’s a Wrap Utilizes the best PHP has to offer

    Lightweight and crazy fast Well designed API with great docs Go make cool shit
