I was having problems configuring XDebug to begin with, but found out I needed to enclose the zend_extension directory parameter in double quotes and then reboot the computer to get it to work.
Then, I was having problems with getting XDebug to work, and from looking at the threads here, it seemed to be a common problem. I was in the process of trying to see if anyone had come up with a solution when I stumbled across one on my own. I was operating with following setup:
OS: Windows 7 64bit Home Premium edition
HTTP Server: Apache 2.2
PHP version: 5.3.1 VC6.0 Threadsafe
IDE: Dev-php 2.3.2 with XDebug installed
I had originally configured my Apache server to listen on port 80, and Dev-php as well. I kept getting a port conflict error every time I tried to save my config settings. I was also experiencing the following error: My activate debug button would not gray out when I clicked on it. I finally tried changing the web server port in Dev-php and the Apache server's listening port in the http.conf file to 8080 and everything came alive.
Thanks for your report and your looking at threads.<p>
But, we wrote about all that sort of things: PHP-engine, Xdebug engine, web-server, internal preview, …
And here is the of the documentation.<p>
Hope this helps,<br>
