Mod_layout, Escaping PHP Without ?>

I've installed mod_layout and it works correctly except if I use > in my PHP scripts for it. For some reason it is escaping from PHP and printing everything after >. So that leaves me unable to use the greater than sign to evaluate expressions or problems.

Example:

Code:
<?php
$a = 2;
$b = 3;

if($b > $a){
echo 'Greater than';
}
?>
Everything after > would be printed to the screen instead of being parsed through PHP. I am lost as what to try, I've tried all the normal escape characters but I must be missing something.
