Answer 1

PHPStorm has a build-in tool in Run > Web Server Debug Validation.

It helped me to solve my problem.

Answer 2

I also obtain this error message.
Also was troubles with the php.ini but more subtle.

Try to find and delete a row like this

extension=php_xdebug-...

Consider to look at my answer here for details "Xdebug - command is not available".

Answer 3

Try changing the xdebug listen port in your php.ini and your IDE.

Running Mac Yosemite, for me the problem was that I installed with homebrew, following a guide that used php-fpm, which uses port 9000 by default (which conflicts with the xdebug default port)... Changing my xdebug.remote_port to 9001 and changing the xdebug port in phpstorm fixed the problem, though I suspect this issue could happen for anyone in any IDE. I googled for the better part of a day and didn't see this solution (since I believe it's so specific to install method).. but I hope it helps someone.
