Edit report at https://bugs.php.net/bug.php?id=66961&edit=1 ID: 66961 Updated by: yohgaki@php.net Reported by: thomas dot stavang dot pedersen at gmail dot com Summary: get_object_vars() returns object references -Status: Open +Status: Verified Type: Bug Package: Unknown/Other Function Operating System: Linux, Fedora 19 PHP Version: 5.5.10 Block user comment: N Private report: N New Comment: http://3v4l.org/H7h4N It seems PHP does changes value while HHVM does not. Previous Comments: ------------------------------------------------------------------------ [2014-03-26 14:30:16] thomas dot stavang dot pedersen at gmail dot com Description: ------------ get_object_vars() returns an array which can be manipulated as you would using a normal object. Manipulating the resulting array should not manipulate the object itself, but it does in this case. Test script: --------------- class Foo { public $bar = null; public function __construct() { $this->bar = new DateTime(); // Now $this->far = &$this->bar; } } $foo= new Foo(); var_dump($foo); $vars = get_object_vars($foo); $vars['bar'] = new DateTime('2014-03-25'); var_dump($foo); Expected result: ---------------- $foo->bar should not be altered, as we are only changing the get_object_vars() array, but it is. Actual result: -------------- $foo->bar (and $foo->far) gets a new value. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66961&edit=1
