I use PHPStorm along with Xdebug to step through my code. PHPStorm is running on a Windows 7 machine, and my local webserver is running on a separate CentOS 6.4 machine. I've done a phpinfo(); to verify that Xdebug is being loaded by PHP, and it is. The following are the settings for my Xdebug in the PHP.ini: 

    [xdebug]
    zend_extension="/usr/lib/php/modules/xdebug.so"
    xdebug.remote_enable = 1
    xdebug.remote_port = 9000
    xdebug.remote_host = "192.168.1.130"
    xdebug.remote_log = "/var/log/httpd/xdebug_log"
I similarly setup PHPStorm to use my CentOS server as the debugging server, and I listen for connections. I assigned static IPs to both of these machines. Using a Chrome Xdebug plugin to set the appropriate cookies, I attempt to set a breakpoint, but nothing happens. When I go to look in /var/log/httpd/xdebug_log (which has 777 permissions), nothing is written there. I've opened up port 9000, and I can telnet from my CentOS machine back to my Windows machine on port 9000 no problem. I also set SELinux to permissive, but to no avail.

Any ideas what could be happening here?

    Well ... if you have NOTHING in xdebug_log file ... then xdebug simply not getting debug request (cookie/get/post parameter etc). You can FORCE debug mode: xdebug_break(); to programmaticaly hit breakpoint or with xdebug.remote_connect_back = 1 or xdebug.remote_autostart = 1 (check docs for details). SELinux definitely can cause issues (not expert at all in this regard). In any case, have a look at this as well: blog.jetbrains.com/phpstorm/2013/07/… Commented Jul 30, 2013 at 9:59
  • I tried your suggestions, but still no luck. when I call xdebug_var_dump() or xdebug_is_enabled(), I'm getting values indicating that xdebug is working. However, PHPStorm is not connecting. I've quadruple checked my remote server settings, and I can 100% tell you that they are correct. Commented Jul 31, 2013 at 23:08
  • I'm shaking my head at myself... I rebooted CentOS, and all is working now. Ugh, I really need to start following my own advice and try a reboot before wasting your guys' time ;-) Commented Jul 31, 2013 at 23:27
  • This is not a waste of time, this is a valid solution to your problem and an important reminder to always 'check the plug'. Commented Jun 28, 2015 at 14:36

Try to configure your project in PhpStorm

  1. Open Settings->Languages & Frameworks->PHP->Debug
  2. Uncheck the "Ignore external connections through unregistered server configurations" option
  3. OK

could you please add a "why this works" to this answer?
Checkbox "Ignore external connections through unregistered server configurations" means that domain name of your local website (you trying to debug) must be listed in the PHP -> Servers (in phpstrom config). If no, then your website will be ignored by phpstorm.
Thank you, I was testing xdebug with a random file not present inside the project andit was working for me with the browser addon, but then I went ahead and created my own debug server in config, for the file I was testing and then it seems PHPStorm might have automatically enabled the option to ignore external connections... I disabled it and it fixed the issue
xdebug.discover_client_host = true

Add to your php.ini:

xdebug.mode=debug

I was having the same issue, below are the steps I performed to resolve it:

  1. Make sure you have xdebug installed and in php.ini uncomment xdebug.mode=debug
  2. Open Settings->Languages & Frameworks->PHP->Debug, Assign Debug Port value, you can find this port from php.ini. In my case, it was 9002
  3. Now Validate debugger configurations - here you need to add the path to your web application files and URL. Click validate.
  4. Now Start Listening -> Enable listening for PHP Debug Connection.

After this setup you can set a break point and start debugging with XDEBUG.

In my case, i added folder that im debugging to exclusive, so it return 502 or blank page when i put breakpoint. Remove exclusive folder and everything working.
