#19930 [Bgs->Opn]: list() can't get values from associative arrays

ID: 19930 User updated by: flying@dom.natm.ru Reported By: flying@dom.natm.ru -Status: Bogus +Status: Open Bug Type: Arrays related Operating System: Windows 2000 PHP Version: 4.2.3 New Comment: Yes, i know and this is a reason for this bug. Instead of requiring numeric indexes list() must invoke array_values() transparently if it is used in combination with associative array. Otherwise it mean that PHP actually have 2 types of arrays with partial compatibility. These duplicates of array values looks very silly for me, there must be one way of handling every array without necessarity of its additional analize into user's code.

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 list() requires numeric index. That's why pg|mysql_fetch_array(),etc returns both numeric and string indexed element. ------------------------------------------------------------------------ [2002-10-16 05:02:42] flying@dom.natm.ru list() function can only operate with indexed arrays, but it must also work with associative arrays, otherwise it can cause confusions. Take a look at the following example: <?php $array1 = array('aaa','bbb','ccc'); $array2 = array('a'=>'aaa','b'=>'bbb','c'=>'ccc'); list($a,$b,$c) = $array1; echo "$a\n$b\n$c\n"; list($a,$b,$c) = $array2; echo "$a\n$b\n$c\n"; ?> First list() invocation works well but second one throws notices about undefined array indexes and don't work at all. As a workaround it is possible to use: list() = array_values($array); but it is not a way to go. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19930&edit=1
