#44854 [Opn->Bgs]: access to a private/protected property should not be allowed

ID: 44854 Updated by: derick@php.net Reported By: doctorrock83 at gmail dot com -Status: Open +Status: Bogus Bug Type: Class/Object related Operating System: Windows XP PHP Version: 5.2.5 New Comment: Thank you for taking the time to write to us, but this is not a bug. 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 This is expected as access control is *class* based, and not object based. Previous Comments: ------------------------------------------------------------------------ [2008-04-28 13:40:16] doctorrock83 at gmail dot com Description: ------------ In some cases, PHP doesn't handle the visibility correctly, allowing a private or protected member to be directly accessed via $obj->prop This seems to happen when a class stores instances of itself and tries to access their properties. Reproduce code: --------------- <?php class bar { private $a; private $children = array(); public function __construct($infiniteDepth) { $this->a = 'foo'; if ($infiniteDepth) $this->children[] = new self(false); } public function privateAcces() { foreach ($this->children as $child) { echo $child->a; // here is the bug } } } $t = new toto(true); $t->privateAcces(); Expected result: ---------------- fatal error as we access the private 'a' property from a non-$this context Actual result: -------------- the property gets read correctly, as if it was public ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44854&edit=1
