Edit report at https://bugs.php.net/bug.php?id=62703&edit=1 ID: 62703 Updated by: aharvey@php.net Reported by: spam02 at live dot com Summary: substr() length=null -Status: Open +Status: Wont fix Type: Bug Package: Strings related Operating System: Linux PHP Version: 5.3.15 Block user comment: N Private report: N New Comment: This is documented behaviour: if the length parameter weakly evaluates to int(0), false, null or an empty string may be returned. We can't fix this without a BC break, and I don't think it's worth it, personally.
