#46283 [Opn->Fbk]: array_merge_recursive() Warning recursion detected in...

ID: 46283 Updated by: lbarnaud@php.net Reported By: name at email dot com -Status: Open +Status: Feedback Bug Type: Arrays related Operating System: * PHP Version: 5CVS-2008-11-17 New Comment: I can't reproduce with 5.3CVS (no warnings). The weird output is caused by two null bytes and the class name added to private properties. You get the same output when casting a class to an array.

You're passing an object to a function expecting arrays and think it will work..? ------------------------------------------------------------------------ [2008-10-12 22:14:15] name at email dot com Description: ------------ Calling array_merge_recursive() produces an unclear warning ("recursion detected in"...) and seems to be breaking the script. The above happens if two conditions are met: 1. there is a private/protected data member in the object (see code). 2. the merged arrays contain at least one same string as key. * please note: following code reproduces this problem on the latest snaps of both 5.2.6 and 5.3 Reproduce code: --------------- class A { private $variable; public function __construct() { $this->variable = 'foo'; } } $x = new A; $b = array_merge_recursive(array("name"=>$x),array("name"=>$x)); var_dump($b); Expected result: ---------------- see 'Actual result' below... Actual result: -------------- array(1) { ["name"]=> array(1) { ["�A�variable"]=> array(2) { [0]=> string(3) "foo" [1]=> string(3) "foo" } } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46283&edit=1
