Edit report at https://bugs.php.net/bug.php?id=67419&edit=1 ID: 67419 Updated by: requinix@php.net Reported by: rilyu at sina dot com Summary: foreach access the array problem -Status: Open +Status: Not a bug Type: Bug Package: Arrays related Operating System: Windows 7 PHP Version: 5.5.13 Block user comment: N Private report: N New Comment: That's references for you. After the first loop ends $row will still be a reference to the last element in the array, so when the second loop sets $row to each of the values it finds in the array, the referenced value gets updated. unset($row) after the first loop. Better yet, don't use references where you don't need them.
