The
Man

7. Laravel About

• Released in July 2011
• Easy to understand for both code and documentation (fun to develop with)
• Composer-based and friendly
• Promote S.O.L.I.D design pattern
• Supported by a thriving community
• Member of PSR project
• Licensed MIT

8. Some Laravel Fancy Features
• Flexible Routing
• Dependency Injection / IoC Container
• Event Binding
• Cache Drivers
• Queue Drivers
• Authentication Drivers
• Powerfull ActiveRecord ORM
• Command-line utility
• Testing Helpers
• ...

9. THE PHILOSOPHY
“Any time that I have to do something that is a pain...
it puts a seed in my head to work it into Laravel”
• Reducing developmental pain points
• Simple to use / expressive API
• Give the developer the control over their architecture
• Grows with the developer

10. Laravel Become Mainstream
• 294 Contributors To Laravel 4.x
• 7.000 Closed Issues
• Most Starred PHP Project on Github
• Most Watched PHP Project on Github
• 1.2 Millions+ Composer Installs
Source : Laracon 2014 Keynote – Taylor Otwell

11. Installation
• Install Composer
• Install Laravel
• Laravel Installer using composer
composer global require "laravel/installer=~1.1"
composer create-project laravel/laravel laravel-demo
• Git clone
https://github.com/laravel/laravel
• Download
https://github.com/laravel/laravel/archive/master.zip

12. PHP >= 5.4
MCrypt PHP Extension

13. Simplicity From Download To Deploy

14. Laravel Homestead

15. Laravel Homestead
• Official Laravel Vagrant Box (http://www.vagrantup.com)
• Pre-Package for Super Fast Installation
• Dead Simple Configuration File
• All Your Project On a Single Box
• It’s Heavenly :D

16. Laravel ForgeServers for Artisans | forge.laravel.com

17. Laravel Forge
• Instant PHP Platforms
• Cloud of your choice

18. Expresiveness
$articles = Article::where('author','=','otwell')
->orderBy('date','desc')
->skip(5)
->take(5)
->get();
Auth:check();
Cache::forever(‘the_man’,’otwell’);
Redirect::to('user/login')->with('message', 'Login Failed');

19. Powerfull Command line Tool
• Based off symfony’s console
component
• Allow a number of application
management task to be run
from the CLI (code generation,
DB process,etc)
• Easly customizable-write your
own

20. Interactive shell (tinker)

21. Laravel Project Structure
> composer update

22. ROUTING & FILTERING

23. Routing
• Implicit Routing
• Routing to Controller
• Routing to Resources (REST)

24. Implicit Routing
Route::get('news',function(){
return '<p>News Page</p>';
});
Route::get('news/{id}',function($id){
return 'News with id '.$id;
})->where('id','[0-9]+')

25. Routing to Controller
Route::controller('news','NewsController');
Route::controller('login','LoginController');
Route::controller('admin','AdminController');
class NewsController{
public function getIndex(){...}
public function getArticles(){...}
public function postComment(){...}
public function getAuthorProfile(){...} //news/author-profile
}

26. Route to Resources (REST)
Route::resource('news','NewsController');
class NewsController{
public function index(){...}
public function create(){...}
public function store(){...}
public function show(){...}
public function edit(){...}
public function update(){...}
public function destroy(){...}
}

27. Route Filtering
Route::filter('old', function()
{
if (Input::get('age') < 200)
{
return Redirect::to('home');
}
});
Route::get('user', array('before' => 'old', function()
{
return 'You are over 200 years old!';
}));

28. • Easy to understand
• Expressiveness and Elegance
The Syntactic Sugar
Auth::check();
Input::get();
Cookie::make();
Event::subscribe();
Pesan::kirim(); // your own facade example

29. Static Method !?
App:bind('mailer',function(){
return new Mailer();
});
Route::filter('auth',function(){
if(Auth::guest())
return Redirect::action('AuthController@getLogin');
});
Route::model('user','User');

30. Facades
Enable you to hide complex interfacec behind a simple one.

31. What Really Happening?
// This Command
Route::get(‘/’,’HomeController@getIndex’);
// Is doing this.
$app->make(‘router’)->get(‘HomeController@getIndex’);
// This Command
Input::get(‘email’);
// Is doing this.
$app->make(‘request’)->get(‘email’);
// This Command
$appName = Config::get(‘application.name’);
// Is doing this.
$fileSystem = new Filesystem(...);
$fileLoader = new Fileloader($fileSystem);
$config = new Config($fileLoader,’dev’);
$appName = $config->get(‘application.name’);

32. MODEL
VIEW
CONTROLLER

33. •Model
•View
•Controller
•Eloquent ORM
•Blade Engine
•Controller

34. Model
class People extends Eloquent {
protected $table = 'people';
protected $primaryKey = 'id';
public function summary(){
return truncate($this->content,100);
}
}

35. • Query Builder
• Eloquent

36. Controller
• Basic Controller
• Controller Filter
• Implicit Controller
• RESTful Resource Controller

37. View
• Blade is a quick and relatively simple template engine for rendering
you views.
• Features many of the core functions found in other popular engines
such as twig and smarty
• Since blade views are PHP scripts, you can use PHP code directly in
your templates (with caution)
• Inheritance-driven to allow for multiple layouts, sections, etc

38. Layout
<html>
<head></head>
<body>
<header>This is Header</header>
<section class="content">
@yield('content')
</section>
<footer>copyright@made by cool me</footer>
</body>
</html>
@extends('layout')
@section('content')
<p>This is partial content</p>
@stop
layout.blade.php
home.blade.php

ROLLBACK MIGRATION
SEEDING DATA

40. MIGRATIONVersion Control for Database Schema
WHY
ARE
GOOD?

41. Schema Builder
public function up()
{
Schema::create('people', function(Blueprint $table)
{
$table->increments('id');
$table->string('first_name');
$table->string('last_name');
$table->string('role')->default('star');
$table->string('bio')->nullable();
});
}
public function down()
{
Schema::drop('people');
}

42. IoC Container( Inversion of Control )

43. Quick word on Dependencies
• A dependency is when one component (typicaly an object) relies on
another for its operation.
• Dependencies should be passed (injected) into an object via its
constructor or setter methods and not instatiated inside it
• Directly instatiating dependencies is considered bad practise as it
reduces scalability and flexibility, plus it make objects difficult to test
in isolation.

44. Inversion of Control
public function sendEmail(){
$mailer = new Mailer();
$mailer->send();
}
public function sendEmail(){
$mailer = App::make(‘mailer’)
$mailer->send();
}
Hard-coded source dependecy
IoC Resolution

45. Dependency Example
class Computer{
protected $processor;
public function __construct(){
$this->processor = new ProcessorIntelI7();
}
}
class Computer{
protected $processor;
public function __construct(ProcessorInterface $processor){
$this->processor = $processor;
}
}

46. App::bind('keranjang_belanja',function($app){
return new KeranjangBelanja(new Pelanggan,new Belanjaan);
});
$keranjangBelanja = App::make('keranjang_belanja');

47. Singletons
App::singleton('user_session',function($app){
return new UserSession($_SESSION['REMOTE_ADDR']);
});
// First call to creates the object...
$userSession = App::make('user_session');
// Second call just fetches...
$userSession = App::make('user_session');

48. IoC Automatic Dependency Resolution
If you type-hint the dependencies passed into a constructor then
Laravel can do the rest!
class Computer{
protected $processor;
public function __construct(ProcessorInterface $processor){
$this->processor = $processor;
}
}
App::bind('ProcessorInterface','ProcessorIntelI7');
$computer = App:make('Computer');

49. IoC Container + Facades = Laravel
