Answer:
If you have installed the xdebug, and the PHP interpreter show the following warning message every time you execute the php command.
Xdebug MUST be loaded as a Zend extension
It can be solved by adding the following line in your php.ini (Replace the path of you xdebug.so if they are different.)
zend_extension="/usr/local/php/modules/xdebug.so"
And remember to remove any statement like the following which caused the problem..
extension="xdebug.so"
