ID: 49284 User updated by: dhaval4linux at yahoo dot com Reported By: dhaval4linux at yahoo dot com Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5.2.10 New Comment: Got it from Bug http://bugs.php.net/bug.php?id=48937 Thanks Previous Comments: ------------------------------------------------------------------------ [2009-08-19 08:04:37] dhaval4linux at yahoo dot com Can I ask Why it is Bogus? although its showing warning. ------------------------------------------------------------------------ [2009-08-18 11:58:51] jani@php.net Thank you for not searching before submitting another duplicate bogus report. This is not a bug. ------------------------------------------------------------------------ [2009-08-18 08:08:07] dhaval4linux at yahoo dot com Description: ------------ Look at below code. on E_STRICT error_reporting either explode or array_pop is throwing warning about passed by reference. explode may returning something odd which causes array_pop to throw this warning. else explode may have problem which throws this warning. Below example shows both way with explode and without explode. with explode it shows warning while without that it works fine. Tested same thing on PHP version 5.2.10 and 5.2.6 Reproduce code: --------------- <?php error_reporting(E_ALL|E_STRICT); $stack2 = array("orange", "banana", "apple", "raspberry"); $stack = "orange_banana_apple_raspberry"; var_dump(strtolower(array_pop(explode('_',$stack)))); var_dump(strtolower(array_pop($stack2))); ?> Expected result: ---------------- string(9) "raspberry" string(9) "raspberry" Actual result: -------------- Strict Standards: Only variables should be passed by reference in /root/test.php on line 5 string(9) "raspberry" string(9) "raspberry" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49284&edit=1
