自己的软件包中的调试断点：Symfony 2.7 + PHPStorm 9 + Xdebug 2.2

Question

this is the first time I try to debug a Symfony 2.7 installation with xdebug inside PHPStorm 9.0. Apache is running on the same system where PHPStorm is installed. The basic setup works so PHPStorm is connected with xdebug, breaks on the first line and stops on the next breakpoint when I press F9. My problem is: the debugger does not stop inside my own bundles in Symfony2. It seems that the Symfony2 structure "confuses" PHPStorm. The debugger only stops in some main symfony2 files like app.php or AppKernel.php.

Let's start with my configuration:

• PHPStorm 9.0
• Apache/2.2.22 (Debian)
• Xdebug v2.2.1
• PHP Version 5.4.45-0+deb7u1
• Iceweasel 31.8.0 with Booklets ( https://www.jetbrains.com/phpstorm/marklets/ )

xdebug.conf

zend_extension=/usr/lib/php5/20100525/xdebug.so
xdebug.remote_enable=1
xdebug.profiler_enable=1
xdebug.remote_log=/var/log/xdebug-remote.log
xdebug.remote_autostart=0
xdebug.var_display_max_children=512
xdebug.var_display_max_data=32000
xdebug.var_display_max_depth=8

Everything in xdebug remote log looks fine and I find all my breakpoints which I set in PHPStorm. I also can open files with VIM using the file:// path which I can see inside the xdebug log.

My conclusion : there is no mapping problem, right? To be really save I mapped all folders in PHPStorm settings. It still does not work...

Breakpoint in symfony/app/AppKernel.php works:

<- breakpoint_set -i 11 -t line -f file:///var/www/myDomain.de/symfony/app/AppKernel.php -n 23
-> <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="breakpoint_set" transaction_id="11" id="110380033"></response>

Breakpoint in own bundle in SmartphoneController.php does not work (PHPStorm debugger does not stop):

<- breakpoint_set -i 12 -t line -f file:///var/www/myDomain.de/symfony/src/Pce/Bundle/BackendBundle/Controller/SmartphoneController.php -n 32
-> <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="breakpoint_set" transaction_id="12" id="110380034"></response>

To be sure that the codeline is executed I saved some test string in a global $_SERVER variable:

$_SERVER['TEST_FOR_DEBUG'] = 'Am I executed? YES!';
var_dump($_SERVER['TEST_FOR_DEBUG']);

My conclusion : the xdebug - PHPStorm setup generally works (debugger stops in AppKernel.php).

Ok, maybe there is a problem with Symfonys caching and PHPStorm comes into trouble referencing the right files. I found these articles to disable Symfonys caching to "help the IDE":

• Debugging Symfony components: https://www.adayinthelifeof.nl/2014/12/31/debugging-symfony-components/
• Disabling Symfony Cache: github.com/symfony/symfony-standard/pull/393
• How to Optimize your Development Environment for Debugging: symfony.com/doc/current/cookbook/debugging.html
• Symfony2 aided by PhpStorm: craftitonline.com/2011/06/symfony2-aided-by-phpstorm/

Based on these articles I called the Dev-Environment (app_dev.php) and disabled the caching before:

$loader = require_once __DIR__.'/../app/autoload.php';
Debug::enable();
require_once __DIR__.'/../app/AppKernel.php';
$kernel = new AppKernel('dev', true);
// CHANGE: Comment the next line to disable cache loading
//$kernel->loadClassCache();
$request = Request::createFromGlobals();

No luck! Does anybody know what I can do?

Thanks to LazyOne! I chose another line in my Controller where a simple variable is set. I spent many hours trying to understand why the debugger does not stop at a part of my code where a lot of Doctrine objects are handled. Maybe to complex for PHPStorm.

Read the comments of my question:

• try xdebug_break();
• set breakpoint on "simple" code lines
