Bug description:Division by zero when using % operator.
Description:
------------
Asume $f[1] = ""
I get a "Division by zero" error when i do this:
$overflowsimulation = (((strlen($f[1])) + 2147483648) % 4294967296);
In fact, i get it even if i do this:
$overflowsimulation = (2147483648 % 4294967296);
Thanks.
Test script:
---------------
<?php
$f = "";
$osim = (((strlen($f)) + 2147483648) % 4294967296);
echo $osim;
?>
Expected result:
----------------
0
Actual result:
--------------
