And to make the production environment as fast as possible, Symfony creates big PHP files in your cache containing the aggregation of PHP classes your project needs for every request. However, this behavior can confuse your debugger, because the same class can be located in two different places: the original class file and the big file which aggregates lots of classes.

This recipe shows you how you can tweak this caching mechanism to make it friendlier when you need to debug code that involves Symfony classes.

The app_dev.php front controller reads as follows by default:

1
2
3
4
5
6
7
8
9
// ...

$loader = require __DIR__.'/../app/autoload.php';
Debug::enable();

$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
$request = Request::createFromGlobals();
// ...

To make your debugger happier, disable the loading of all PHP class caches by removing the call to loadClassCache():

1
2
3
4
5
6
7
8
// ...

$loader = require_once __DIR__.'/../app/autoload.php';
Debug::enable();

$kernel = new AppKernel('dev', true);
// $kernel->loadClassCache();
$request = Request::createFromGlobals();

If you disable the PHP caches, don’t forget to revert after your debugging session.

Some IDEs do not like the fact that some classes are stored in different locations. To avoid problems, you can tell your IDE to ignore the PHP cache file.
