#44180 [Opn->Bgs]: key in an array cannot be a reference in foreach loop

ID: 44180 Updated by: johannes@php.net Reported By: martin dot koranda at gmail dot com -Status: Open +Status: Bogus Bug Type: Feature/Change Request Operating System: linux PHP Version: 5.2.5 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The array key is not to be changed afterwards - especially since an array key can only be string or iteger and we can't really pevent the write access to references.

Reproduce code: --------------- foreach($arr as &$key => $val) { ... } Expected result: ---------------- change keys inside the foreach loop Actual result: -------------- Fatal error: Key element cannot be a reference ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44180&edit=1
