ID: 21998 Updated by: magnus@php.net Reported By: php@alterego.dp.ua -Status: Open +Status: Analyzed -Bug Type: Scripting Engine problem +Bug Type: Arrays related Operating System: all PHP Version: 4.3.0 -Assigned To: +Assigned To: sniper New Comment: Array related. One of these commits broke it. revision 1.180 date: 2002/08/01 17:34:31; author: rodif_bl; state: Exp; lines: +12 -15 array_pop wasnt setting next index ---------------------------- revision 1.179 date: 2002/08/01 16:44:47; author: sniper; state: Exp; lines: +1 -4 That was not correct.. ---------------------------- revision 1.178 date: 2002/08/01 16:39:52; author: sniper; state: Exp; lines: +5 -2 Reset index when doing array_pop() Previous Comments: ------------------------------------------------------------------------ [2003-02-01 13:42:12] php@alterego.dp.ua <? $a = array("a", "b", "c"); each($a); array_pop($a); var_dump(each($a)); ?> This prints "bool(false)" in 4.3.0 (current element pointer points somewhere out of the array) and var_dump($a[0]) in 4.2.3 (array is reset after array_pop). I had to add many additional reset()'s after installing 4.3.0. How array_pop() (and may be others) affects current element pointer is not documented, so this behavior is not a bug. The only purpose of writing all this is that I want to know how array_pop() will work in future PHP releases. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21998&edit=1
