Hello.

According to dbg-wizard.php I have the following settings:

PHP Version: 5.3.1
Web Server: Apache/2.2.14 (Win32) PHP/5.3.0
Server Name: tm
Platform: WINNT/x86_VC9
Your Client IP Address: 127.0.0.1
Your Server IP Address: 127.0.0.1
Port: 80
Your Web Server is on the same machine with PhpED
Path to website files: D:\Work\www\tm\
Document Root is: D:\Work\www\tm\
Your PHP.INI file is: C:\Program Files\NuSphere\PhpED\php53\php.ini
PHP extensions directory is: C:\Program Files\NuSphere\PhpED\php53\extensions

Now I'm trying to set up debugger and I
1) copied dbg-php-5.3.dll into C:\Program Files\NuSphere\PhpED\php53\extensions
2) added the following lines to php.ini :

zend_extension="C:\Program Files\NuSphere\PhpED\php53\extensions\dbg-php-5.3.dll"
[debugger]
debugger.hosts_allow= 127.0.0.1 localhost
debugger.hosts_deny=ALL
debugger.ports=7869

3) restarted wed server

and NOTHING HAPPEND!!! I mean that debugger has not been set up. (I see just "This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies" in phpinfo)
I can't understand what I've done wrong because I've followed "dbg-wizard.php" file instructions step by step.
I'm looking forward for any suggestions. Thanks.

I've taken a look to apache's log and see the following line:

Failed loading C:\Program Files\NuSphere\PhpED\php53\extensions\dbg-php-5.3.dll

Any ideas why this dll cannot be loaded?
Probably the problem connected with web server?

May be someone who doesn't have problems with debugger instalation will share with "dbg-php-5.3.dll" file from "...\debugger\server\Windows\x86_VC9\" dir ?
Please!!! I'll be very grateful...

I'm have same problem.

Error reported in logs after stoping Apache

I have the same problem too – Windows 7 Home Premium x64 + PHP 5.3.1 (VC9 x86 Thread Safe) = not working.
After using VC6 build (instead of VC9) everything works fine for me.

Thanks a lot. It's realy works. But I also had to remove php5ts.dll from C:\Windows\System32.

Have the same configuration and had the same problem.
VC9 build of php_dbg.dll didn't work but VC6 version seems to work fine.
Thank you!
