my php version is PHP Version 5.3.6.
5.3.6
Xdebug setting in php.ini:
[Xdebug] zend_extension_ts=\"D:\\php\\ext\\php_xdebug-2.1.2.dll\" xde
Looks like you just need to download the correct version of xdebug for your version of Windows / PHP. There are VC9 builds here, just select the appropriate one for 32 or 64 bit.
