AH! I found a nice as hell function (which will help me A WHOLE LOT!!) Thank you thank you thank you for posting the question! here is the fix!
<?php
$string = "BLah blah blah \" blah blah \"";
$position = strpos($string, chr(34));
echo $position;
?>
Use chr(34) to look for double quotes ", but it still only looks for the first one... You might want to use a different function, hope it helps!
