- Previous Comments: ------------------------------------------------------------------------ [2008-09-10 16:29:17] bastard dot internets at gmail dot com Found http://bugs.php.net/bug.php?id=4116 Not a bug, but working as it should. Third parameter must be passed by reference into array_walk function itself to be passed by reference on to the callback function. Closing case. ------------------------------------------------------------------------ [2008-09-10 06:44:50] bastard dot internets at gmail dot com Fixing email contact. ------------------------------------------------------------------------ [2008-09-10 05:45:37] bastard dot internets at gmail dot com Description: ------------ When array_walk function is used inside __construct function of an object, array_walk allows passing of its third parameter to the user defined function by reference. This is expected. In any other case, function, or scope, this parameter cannot be passed by reference, instead passing by value yet producing no error even when the user defined function demands passing this third parameter by reference. Possibly similar to bug 45780, but unlikely due to function scope behaviour. Testing on php 5.2.4 (cvs/snap unknown); apache 2.2; ubuntu 8.04 server. PHP packaged with ubuntu 8.04 lamp. Reproduce code: --------------- <?php class ClassTest { public $val_1 = null; public $val_2 = null; function __construct($array) { $class_test_array = array("val_1" => 1, "val_2" => 2, "val_3" => 3); array_walk($class_test_array,create_function('$v,$k,&$that','if (property_exists($that,$k)) {$that->$k = $v;}'),$this); } } function alter_test_array($val, $key, &$test_array) { $test_array[] = $val; } $class_test_obj = new ClassTest(); $normal_test_array_1 = array(1,2,3); $normal_test_array_2 = array(); $normal_test_array_3 = array(); array_walk($normal_test_array_1, create_function('$val,$key,&$test_array', '$test_array[] = $val;'), $normal_test_array_2); array_walk($normal_test_array_1, alter_test_array, $normal_test_array_3); Expected result: ---------------- $class_test_obj === object(1,2) $normal_test_array_2 === array(1,2,3) $normal_test_array_3 === array(1,2,3) Actual result: -------------- $class_test_obj === object(1,2) $normal_test_array_2 === array(0) $normal_test_array_3 === array(0) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46037&edit=1
