Laravel

Laravel is a PHP framework using elements from other tools such as Symfony 2 and Bootstrap . The documentation on this framework can be found on multiple places on the Internet. But to use Laravel on an OS/X Mac in combination with MAMP-PRO may cause some difficulties.

Artisan

Artisan is the command line tool for Laravel can be used for:

• Generating a boilerplate controller
  i.e. $ php artisan controller:make user
• Managing database with migrations
  i.e. $ php artisan migrate:install
• Filling the database with basic data for testing via database seeds
  i.e. $ PHP artisan db:seed
• Running unit tests
  i.e. $ php artisan test
• Routing
• Configuring an application
• Creating new artisan commands
• Creating a new workbench package
• Maintenance
  i.e. $ php artisan down

When trying to run the command line tools of Laravel I got an error:

   $ php artisan 
   Mcrypt php extension required.
   ...

The problem is caused by the fact that the used version of PHP is not the correct one. First try:

  $ php -v
  PHP 5.4.30 (cli) (built: Jul 29 2014 23:43:29) 
  Copyright (c) 1997-2014 The PHP Group
  Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies
     with Xdebug v2.3.0dev, Copyright (c) 2002-2013, by Derick Rethans

Now look in the Application directory of MAMP

  $ la /Applications/MAMP/bin/php
  total 0
  drwxrwxr-x  6 HaFrMpro  admin  204 Jan 22  2013 php5.2.17
  drwxrwxr-x  6 HaFrMpro  admin  204 Jan 22  2013 php5.3.20
  drwxrwxr-x  7 HaFrMpro  admin  238 Jan 22  2013 php5.4.10

Choose the PHP version 5.4.10 and place the following code in you .bash_profile

  export MAMP_PHP=/Applications/MAMP/bin/php/php5.4.10/bin
  export PATH="$MAMP_PHP:$PATH"

Let me know if this helps

MAMP PRO

Larval runs easily on Mac. The only thing you need to do is to ensure that the app/stroage directory is writable. Do:

$ chmod -R 775 app/storage

Magic of Laravel

Laravel's magic works:

• Laravel has a lot of core components
• When any request hits the Laravel framework, it bootstraps and loads its Application class
• Laravel's Application class extends the container class, so the container class is also loaded
• Framework loads and executes the register method of all the service providers that are in the providers array at app/config/app.php
• Each service provider by the Laravel packages has a registered method that binds each of the package classes with the IoC container
• Once each package is bound with the IoC container, you can use packages such as Auth, Cache, and Log in your application

Packages are the easiest way to add third party code in Laravel .

Laravel Request Handling

Request Life Cycle

High level overview of Laravel :

• Request enters public/index.php file (i.e. blog/public/index.php).
• The bootstrap/start.php file (i.e. /blog/bootstrap/start.php) creates Application and detects environment.
• Internal framework/start.php file (i.e. blog/vendor/laravel/framework/src/Illuminate/Foundation/start.php ) configures settings and loads service providers.
• Application app/start files (i.e. blog/app/start/) are loaded.
• Application app/routes.php file (i.e. blog/app/routes.php) is loaded.
• Request object sent to Application, which returns Response object.
• Response object sent back to client.

Start Files

Application's start files are stored at app/start (i.e. blog/app/start/). By default, three are included with your application:

• global.php,
• local.php,
• artisan.php

Application Events

Do pre and post request processing by registering

• before,
• after,
• finish,
• shutdown

application events:

App::before(function($request)
{
    //
});

App::after(function($request, $response)
{
    //
});

Routing

Most of the routes for your application will be defined in the app/routes.php file . The simplest Laravel routes consist of a URI and a Closure callback.

• Basic Routing
• Route Parameters
• Route Filters
• Named Routes
• Route Groups
• Sub-Domain Routing
• Route Prefixing
• Route Model Binding
• Throwing 404 Errors
• Routing To Controllers

Basic GET Route

Route::get('/', function()
{
    return 'Hello World';
});

Basic POST Route

Route::post('foo/bar', function()
{
    return 'Hello World';
});

Registering A Route For Multiple Verbs

Route::match(array('GET', 'POST'), '/', function()
{
    return 'Hello World';
});

Registering A Route Responding To Any HTTP Verb

Route::any('foo', function()
{
    return 'Hello World';
});

Forcing A Route To Be Served Over HTTPS

Route::get('foo', array('https', function()
{
    return 'Must be over HTTPS';
}));

Often, you will need to generate URLs to your routes, you may do so using the URL::to method:

$url = URL::to('foo');

Requests & Input

The request & Input consists on :

• Basic Input
• Cookies
• Old Input
• Files
• Request Information

Views & Responses

Consists on :

• Basic Responses
• Redirects
• Views
• View Composers
• Special Responses
• Response Macros

Controllers

Consists on :

• Basic Controllers
• Controller Filters
• Implicit Controllers
• RESTful Resource Controllers
• Handling Missing Methods

Errors & Logging

The logging and error consists on :

• Configuration
• Handling Errors
• HTTP Exceptions
• Handling 404 Errors
• Logging
