yum install xdebug + xdebug test example for php 5.4

Xdebug  is a nice tool for PHP development. The following is taken from official site:

Xdebug's basic functions include the display of stack traces on error conditions, maximum nesting level protection and time tracking.

There are many ways to install xdebug. Now I give one way to use yum for xdebug installment.

or with enable remi repo

sudo yum --enablerepo=remi install php-xdebug
