Assuming you have PHP installed and updated. If possible update it, or just check your version using your command prompt

<?php
phpinfo();
?>

Run this file from your web server - YOURHOST[:PORT]/check.php?
COPY the output of this page [Simple CTRL+C]

and paste in the box. Click on Analyse my phpinfo() output. This page will give you the instructions to follow for the xdebug installation.[for simplicity name the php_xdebug-VCX-xxx.dll to php_xdebug.dll]

NOTE - in PHP.ini please comment
