Edit report at http://bugs.php.net/bug.php?id=52566&edit=1 ID: 52566 Updated by: aharvey@php.net Reported by: elicon31 at hotmail dot com Summary: Division by zero when using % operator. -Status: Open +Status: Bogus Type: Bug -Package: *Regular Expressions +Package: Scripting Engine problem Operating System: Windows Xp SP3 PHP Version: 5.3.3 Block user comment: N New Comment: On a 32 bit compile of PHP, 4294967296 used in an integer context will overflow to 0, hence PHP believes you're attempting to divide by 0, remembering that modulus is effectively division. Expected behaviour; closing.
