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

Question

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

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

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

Answer 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 ;)

Answer 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.
