I have added following lines into php.ini
[XDebug] zend_extension = C:\\PROGRA~1\\PHP5\\ext\\php_xdebug-2.1.0-5.3-vc9.dll xdebug.remote_enable=on xdebug.remo
I just had the same problem, nothing of this worked for me. I started php in the console and I saw, php was unable to load the dll from the given path. The solution for me was to omit the path information and only load it like this:
zend_extension="php_xdebug-2.2.5-5.5-vc11.dll"
