xdebug

Install xdebug through homebrew or pecl.

// homebrew
brew search xdebug
brew install php55-xdebug
// pecl
pecl install xdebug
//php --ini // this does not work. This will give you a wrong php.ini file. 

Check phpinfo.php to find the Loaded Configuration File. My case is /etc/php.ini.

Add the following at the end of php.ini and restart the server sudo apachectl restart. And check the phpinfo.php again.
