Quick View of the Laravel 4.1 Workflow

Here is a quick view of the Laravel 4.1 workflow when a request is made. It’s probably out of date now.

File: public/index.php

• call composer autoloader (START OF APPLICATION)
• call $app = require(bootstrap/start.php)
• call $app->run():
  • Get request
  • Get response from handled request
  • Send response
  • Terminate stack (END OF APPLICATION)

File: bootstrap/start.php

• create $app
• detect environment
• store array of paths
• call Illuminate/Foundation/start.php
• return $app

File: Illuminate/Foundation/start.php

• turn off PHP error reporting(-1)
• check for mcrypt extension or die
• use 5 namespaces (Request, Facade, AliasLoader, EnvironmentVariables, Repository)
• bind $app (self) to container for use a facade
• if unit testing, bind env to test environment
• clear all facade instances
• set $app as facade application
• register core container aliases (for dependency injection)
• store $_ENV and $_SERVER variables
• bind config repository to container
• register exception handling
• if not testing, turn of display_errors
• set the default timezone
• register the alias loader
• enable HTTP request method override (for PUT and DELETE)
• Register the core service providers (session, caching, encryption, etc)
• once application is booted, call closure:
  • require app/start/global.php (Class Loader, Error logger file, error handler, maintenance mode, app filters)
  • require app/start/{$env}.php (empty)
  • require app/routes.php (application routes)
