Bug #63993 [Nab]: foreach issues notice with main() link

Edit report at https://bugs.php.net/bug.php?id=63993&edit=1 ID: 63993 User updated by: ray dot paseur at gmail dot com Reported by: ray dot paseur at gmail dot com Summary: foreach issues notice with main() link Status: Not a bug Type: Bug Package: SimpleXML related Operating System: Mac PHP Version: 5.3Git-2013-01-15 (snap) Block user comment: N Private report: N New Comment: "this main means it's at the top scope..." What does that mean, in plain language, please? The script fails, and it issues a warning message that refers the client to a page that says, "If you discover such a reference, please » file a bug report, indicating the PHP function caused the error that linked to main() and it will be fixed and properly documented." I'd be grateful for your help, thanks.
