#42409 [Opn->Fbk]: -> operator permanently damaged after assigning value to overloaded variable

ID: 42409 Updated by: jani@php.net Reported By: luke dot mcildoon at niche dot com dot au -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: Windows Vista 32-bit PHP Version: 5.2.3 New Comment: How about you first provided an example script that has some way of working even the wrong way? The one here just says "Fatal error: Call to undefined function session()" Previous Comments: ------------------------------------------------------------------------ [2007-08-24 06:55:54] luke dot mcildoon at niche dot com dot au Description: ------------ I have a class that returns an array by reference using __get(). As soon as you try to set a 2+ dimension on the array, the -> operator returns whatever you tried to assign to the referenced array. ie. session()->session['foo'][] = 'test'; print_r($this->var); #[0] => 'test' print_r($asdf->ghjk); #[0] => 'test' Basically, from any point after the first example line is used, any use of the -> operator, regardless of the object being referenced, will return whatever you tried to assign to the referenced array. Reproduce code: --------------- class session extends ArrayObject { public $data = array(); public function &__get($var) { if($var == 'session') { return $this; } } } session()->session[][] = 'test'; print_r($this->var); print_r($anything->var); print_r($this->foobar); Expected result: ---------------- The actual value of $this->var, then undefined property warnings. Actual result: -------------- [0] => 'test' [0] => 'test' [0] => 'test' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42409&edit=1
