Using XDebug in UEStudio for PHP debugging

Question

I've just downloaded the latest version of UEStudio 09 and am trying out the integrated XDebug features.

I've got xdebug installed, and have verified that via my php_info(). I've written a very basic script to test it out:

1:  <?php
2:  $x = 5;
3:  $y = $x + 1;
4:  $z = 10;
5:  while ($z--) {
6:      echo $x, $y, "<br />\n";
7:  }

I've then started the debugging session and get this message in my output window:

Client: Listening for connection...

I've added a breakpoint on line 4, just to test it out. I then open the file in my browser with the special url parameter:

http://localhost/uetest/index.php?XDEBUG_SESSION_START=test

The script runs normally and it doesn't stop for debugging or anything. The output is this:

Client: Listening for connection...
Client: Connection accepted
Client: Initializing session
==============================
Debug Engine Name: Xdebug
Debug Engine Version: 2.0.3
Protocol Version: 1.0
==============================
Client: Session active
Client Command: Step Into
Client: Exiting debug session
Script completed without errors

If I visit http://localhost:9000/uetest/index.php then UEStudio says "Connection accepted", but from there nothing happens! The script never completes in the browser, and then finally UEStudio crashes.

Any ideas?

Many years ago I used xdebug but recently I've been using the Zend Debugger so I can't remember off hand what I did to get the xdebug.dll to work. I do remember, however, that I did need to add a few entries into the php.ini. The entries that I have for the Zend Debugger are:

For Linux:

[Zend]
zend_extension=/usr/lib/php5/20060613+lfs/ZendDebugger.so
zend_debugger.allow_hosts=127.0.0.1
zend_debugger.expose_remotely=always

For Windows:

[Zend]
zend_extension_ts="c:/php/ext/ZendDebugger.dll"
zend_debugger.allow_hosts=127.0.0.1
zend_debugger.expose_remotely=always

A Google search for "php xdebug php.ini" took me here:

http://devzone.zend.com/article/2930-Debugging-PHP-applications-with-xdebug

Which suggests:

xdebug.remote_enable=On
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"

for xdebug.

Hope this helps.

Last week I evaluated UEStudio as a replacement for Zend Studio 5.5. I setup my XDebug configuration as follows and got it working:

[XDebug]
zend_extension_ts=./ext/php_xdebug.dll
xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.profiler_output_dir=d:/
xdebug.profiler_output_name=timestamp
xdebug.remote_enable=1
xdebug.remote_mode=req
xdebug.remote_autostart=0
xdebug.remote_port=9000
xdebug.remote_host=localhost 
xdebug.idekey=debug

I had to add several settings to my php.ini to get it working. Above is the resulting configuration. Also, I installed XDebug Helper Firefox addon to start debugging right from Firefox. Very convenient.
