ID: 51112 Updated by: ka...@php.net Reported by: post at oliver-schieche dot de Summary: list() misbehaviour Status: Open Type: Documentation Problem -Package: Documentation problem +Package: Scripting Engine problem Operating System: Debian (etch) PHP Version: 5.2.12 New Comment: Can this either be classfied as a scripting engine bug. If it indeed is a documentation issue then re-classify this as a "To be Documented" documentation issue for the developer that picks this one up. Previous Comments: ------------------------------------------------------------------------ [2010-02-22 12:58:56] post at oliver-schieche dot de Why document an obvious bug instead of fixing it? How would you document/explain this? If this works: function ret($array) {return $array;} $b = array('foo','bar'); list($a,$b) = ret($b); But this doesn't: function &ret(&$array) {return $array;} $b = array('foo','bar'); list($a,$b) = ret($b); Then there's a referencing error hidden somewhere... ------------------------------------------------------------------------ [2010-02-22 12:42:52] paj...@php.net That's pretty much the same thing you can see with foreach, the array should not be altered while looping (the array itself, the data of a given element can be altered). No bug here, but should be documented. ------------------------------------------------------------------------ [2010-02-22 12:38:52] post at oliver-schieche dot de Description: ------------ When assigning an array to a list() of variables and using the input array as a member of that list(), unexpected results are returned. Reproduce code: --------------- $b = array('foo','bar'); list($a,$b) = $b; $c = array('foo','bar'); list($c,$d) = $c; Expected result: ---------------- $a == $c == 'foo' $b == $d == 'bar' Actual result: -------------- $a == 'b' $b == 'bar' $c == 'foo' $d == 'bar' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51112&edit=1
