PhpStorm debugger not stopping at BreakPoints; keeps waiting for xdebug _SESSION_

Updated question : PhpStorm | WebMatrix (IISExpress) | Xdebug.remote_port | — Which Port(s) to put where?

I'm running localhost web server on my Windows machine with WebMatrix and IISExpress. I've installed PHP and Xdebug in it and they both are working.

I have a local WordPress install.

I'm now trying to get PhpStorm to debug it using Xdebug.

When I run PhpStorm it launches the web app in the browser with relevant debugging parameters in the browser.

IDE KEY is matching

ide

xdebug.remote_port is configured correctly. (Later I found that this is wrong, but not erroneous. It should be port 9000)

xdebug.remote_port

But it seems Xdebug never gets to communicate with PhpStorm. PhpStorm keeps listening, and the execution runs completely without stopping at any break-points.

PhpStorm

Solution 1:

These lines are crucial to make it work (in php.ini):

zend_extension=/usr/lib/php/extensions/no-debug-non-zts-20121212/xdebug.so
xdebug.remote_autostart = 1 # <-------- THIS
xdebug.remote_enable = 1 # <----------- AND THIS

Without these lines xdebug will never work on phpstorm ;)

Solution 2:

Try changing the xdebug listen port in your php.ini and your IDE.

Running Mac Yosemite, for me the problem was that I installed with homebrew, following a guide that used php-fpm, which uses port 9000 by default (which conflicts with the xdebug default port)... Changing my xdebug.remote_port to 9001 and changing the xdebug port in phpstorm fixed the problem, though I suspect this issue could happen for anyone in any IDE. I googled for the better part of a day and didn't see this solution (since I believe it's so specific to install method).. but I hope it helps someone.

Solution 3:

Took me about an hour until I noticed that this button wasn't activated ;)

"Run" -> "Start Listening for PHP Debug Connections"

Solution 4:

First check for on what port xdebug is working on, you can find it in your php.ini under xdebug.remote_port=9123. As you can see in my case it is set to 9123.
Now open PhpStorm go to php debug, see screenshot: enter image description here
