Symfony2 - Getting Base and Root Paths

gistfile1.php

<?php

// Sometimes you want to be able to get the base path url for your project
// and also another times you just want to get the root folder where
// the symfony2 application is living.
 
// For the first one, the url base path you get it this way:
 
$this->get('request')->getBasePath();
 
// So when loading a page with URL http://localhost/Symfony/web/app.php
// of a symfony2 project located at /var/www/Symfony/ you just get:
 
/var/www/Symfony/web
 
// On the other hand, if you wanted to get the root, that is the filesystem
// path to the root app dir of the application then you would issue something
// like this:
 
$this->get('kernel')->getRootDir();
 
// Which will return for our case this value:
 
/var/www/Symfony/app
 
// Notice this is the app folder and not the root folder per say.
// The app folder is where the autoload and AppKernel are living.
// With that in mind you can navigate below that directory but it is not really
// needed as you would probably be doing things into your app folder anyways.
