Configuring Xdebug with Intellij not working

Question

I have spent hours getting XDebug to work with Intellij, but with no luck unfortunately.

My setup is as follows. I am on a Windows 7 machine, I have Intellij 12 installed. My PHP site runs on a Vmware virtual Linux (debian) box.

I have configured the following Xdebug settings in php.ini.

; xdebug settings
zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.profiler_enable=1
;xdebug.profiler_output_dir="/usr/lib/php5/xdebug-output"
xdebug.remote_host=192.168.1.71
xdebug.show_exception_trace=On
xdebug.remote_handler=dbgp
xdebug.remote_connect_back=1

• 192.168.1.71 is the IP of my virtual server, but I also tried www.local-example.com.
• The site runs ok (I mapped the IP to www.local-example.com)
• phpinfo() tells me PHP is configured with xdebug: (Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies with Xdebug v2.2.3, Copyright (c) 2002-2013, by Derick Rethan
• When I var_dump something it is formatted nicely by xdebug, so this part works.
• I ran my phpinfo() output through the wizard at http://xdebug.org/wizard.php and followed the steps that were suggested to me successfully.
• I had a nice long look at the flowchart here: https://netbeans.org/project_downloads/www/php/debug-setup-flowchart.pdf
• I copied the script at the following url and ran it from the command line: https://blogs.oracle.com/netbeansphp/entry/howto_check_xdebug_installation. When I start the script nothing really happens, so I suppose its listening for connections (I'm not too Linux-savvy :). When I subsequently request one of my site's pages with the XDEBUG_SESSION_START=mysession parameter, the page loads, but very slowly.

All that really happens when I enable the xdebug settings in PHP.ini is that my site becomes slow.

You might wonder why I put Intellij in the title. I was trying to connect to xdebug from Intellij. but I have left intellij, because I think something is wrong with my basic xdebug setup.

Your help will be much appreciated.

correct settings for xdebug on intelliJ IDEA on windows wamp is look for php.ini file find xdebug at bottom,

[xdebug]
xdebug.remote_enable = On
xdebug.profiler_enable = On
xdebug.profiler_enable_trigger = On
xdebug.profiler_output_name = cachegrind.out.%t.%p
xdebug.profiler_output_dir = "c:/wamp/tmp"
xdebug.show_local_vars=0
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9001
xdebug.remote_handler=dbgp
xdebug.remote_autostart=0

The IP that you use, should be the IP of the machine running the IDE - not the one with PHP/Xdebug on it. Xdebug acts as the client, and the IDE as the server, and in order for Xdebug to connect to the IDE/server, it needs to know the IP address of that.

Alternatively, you can set xdebug.remote_conneck_back=1 to let Xdebug use the IP of the machine that makes the browser request (often the same as the machine/IP with the IDE on it).
