note 115453 added to function.array-key-exists

array_key_exists doesn't work with objects implementing ArrayAccess interface. It also ignores possible __get() method in such objects, despite the fact it accepts object as a second parameter. It works only with 'real' properties. <?php class A implements ArrayAccess { public $data; public function offsetExists($offset) { return isset($this->data[$offset]); } public function __get($property) { return $this->data[$property]; } } $a = new A(); $a->data['somekey'] = 1; var_dump(array_key_exists('somekey', $a)); // returns false var_dump(array_key_exists('data', $a)); // returns true ?> ---- Server IP: 72.52.91.14 Probable Submitter: 87.105.187.246 ---- Manual Page -- http://php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/115453 Del: integrated -- https://master.php.net/note/delete/115453/integrated Del: useless -- https://master.php.net/note/delete/115453/useless Del: bad code -- https://master.php.net/note/delete/115453/bad+code Del: spam -- https://master.php.net/note/delete/115453/spam Del: non-english -- https://master.php.net/note/delete/115453/non-english Del: in docs -- https://master.php.net/note/delete/115453/in+docs Del: other reasons-- https://master.php.net/note/delete/115453 Reject -- https://master.php.net/note/reject/115453 Search -- https://master.php.net/manage/user-notes.php
