note 117463 added to function.is-a

I just want to point out that you can replace "is_a()" function with the "instanceof" operator, BUT you must use a variable to pass the class name string. This will work: <?php $object = new \stdClass(); $class_name = '\stdClass'; var_dump(is_a($object, $class_name)); // bool(true) var_dump(is_a($object, '\stdClass')); // bool(true) var_dump($object instanceof $class_name); // bool(true) ?> While this don't: <?php $object = new \stdClass(); var_dump($object instanceof '\stdClass'); // Parse error: syntax error, unexpected ''\stdClass'' (T_CONSTANT_ENCAPSED_STRING) ?> ---- Server IP: 72.52.91.14 Probable Submitter: 81.11.254.148 ---- Manual Page -- http://php.net/manual/en/function.is-a.php Edit -- https://master.php.net/note/edit/117463 Del: integrated -- https://master.php.net/note/delete/117463/integrated Del: useless -- https://master.php.net/note/delete/117463/useless Del: bad code -- https://master.php.net/note/delete/117463/bad+code Del: spam -- https://master.php.net/note/delete/117463/spam Del: non-english -- https://master.php.net/note/delete/117463/non-english Del: in docs -- https://master.php.net/note/delete/117463/in+docs Del: other reasons-- https://master.php.net/note/delete/117463 Reject -- https://master.php.net/note/reject/117463 Search -- https://master.php.net/manage/user-notes.php
