PHPStorm, Xdebug and Google Chrome debugging

Question

I spent all day on this and still cannot get the debugger to work in PHPStorm with Google Chrome. These are the steps I took insofar:

1) Locate xdebug extension after installation:

locate xdebug.so
# => /usr/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so

2) Insert the extension in the php.ini file:

php –ini
# => Configuration File (php.ini) Path: /etc
# => Loaded Configuration File:         /etc/php.ini
sudo vim /etc/php.ini
zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so

3) Confirm xdebug is working:

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 v2.2.3, Copyright (c) 2002-2013, by Derick Rethans

4) Go to PHPStorm > Preferences > Languages and Frameworks > PHP. Click the expand icon (a square box) on the same line as “Interpreter:”. Enter in the php executable path. Click the refresh box so that the debugger version pops up. Click ok and apply.

5) Toggle the “Start Listening for PHP Debug Connections” button in PHPStorm.

6) Set a breakpoint in source code.

7) Go to this url https://www.jetbrains.com/phpstorm/marklets/. Select Generate under Xdebug. Drag "Start debugger", "Stop debugger", and "Debug this page" into the Bookmarks Bar in Google Chrome.

8) I then reload the web page in browser and no break at all. I even tried using the xdebug google chrome extension and that doesn't work either. In their video, however, it worked:

What am I missing here?

Answer 1

First of all take a look at phpinfo() output in the browser:

<?php
    phpinfo(); 
    exit;
?>

Sometimes people edit wrong version of php.ini (for example specified for PHP CLI, not for Web Server) - I met such case several times in my practice. Location of this file depends on your system and to learn more you can read this post: Dude, where's my php.ini?

Then you need to check specified values for your XDebug instance. If you need to change something you should open php.ini and find a section [Xdebug] there.

In author's case we figured out that problem was in xdebug.remote_enable. So the fix was:

[Xdebug]
xdebug.remote_enable = 1

Also I recommend to read "XDebug Installation Guide" from "Jet Brains" team: https://confluence.jetbrains.com/display/PhpStorm/Xdebug+Installation+Guide in which they cover the same steps as I described but in a more detailed manner.
