Can't activate Xdebug on PHP 5.2.17 [closed]

Question

I am running Apache 2.2.19 and PHP 5.2.17. I wanted to configure debugging with Xdebug, so I went to xdebug.org and downloaded: php_xdebug-2.1.2-5.2-vc6-nts.dll (I have php VC6 x86 version). I copied it to c:\Program Files (x86)\php\ext\php_xdebug-2.1.2-5.2-vc6-nts.dll

Edited PHP.ini (added):

[xdebug]
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_log = "c:\host\xdebug.log"
zend_extension_ts="c:\Program Files (x86)\php\ext\php_xdebug-2.1.2-5.2-vc6-nts.dll"

But I still can't see in phpinfo() xdebug information - so it's not working. Apache error log says:

Failed loading c:\Program Files (x86)\php\ext\php_xdebug-2.1.2-5.2-vc6-nts.dll

Are you using thread safe or non-thread safe PHP? It looks like the xdebug dll you downloaded is for non-thread safe. I think you can find this out using phpinfo(). This could be the cause of the problem.

If you are using thread safe PHP then try downloading the thread safe version of xdebug. This could help.

You can download it here: http://xdebug.org/files/php_xdebug-2.1.2-5.2-vc6.dll
