#33495 [Opn->Bgs]: Fatal error: Only variables can be passed by reference with array_shift

ID: 33495 Updated by: tony2001@php.net Reported By: jsheets at idahoimageworks dot com -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: FreeBSD PHP Version: 5CVS-2005-06-27 (dev) 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 error message is quite informative, isn't it ? array_shift() modifies specified variable and "explode('.', 'file.txt')" is definitely not a variable, but an expression.
