php modulo return wrong result

Question

I got problem with this code:

if (!empty($_GET[ \"lic\" ])) $lic = $_GET[ \"lic\" ]; else $e = true;
echo ($lic % 11);

When I post 89

Answer 1

The value "8911076856" is probably above the maximum integer value of your system.

echo ((int)8911076856);

My result is 321142264 on my 32 Bit system.
