note 117491 added to internals2.opcodes.instanceof

I'm commenting here because the note from "admin at torntech" is incomplete. You can perfectly replace "is_a()" function with "instanceof" operator. However you must use a variable to store the class name, otherwise you will get a Parse error: <?php $object = new \stdClass(); $class_name = '\stdClass'; var_dump($object instanceof $class_name); // bool(true) var_dump($object instanceof '\stdClass'); // Parse error: syntax error, unexpected ''\stdClass'' (T_CONSTANT_ENCAPSED_STRING) ?> Please go to Type Operators page for more details about "instanceof": http://php.net/manual/en/language.operators.type.php ---- Server IP: 72.52.91.14 Probable Submitter: 62.235.172.169 ---- Manual Page -- http://php.net/manual/en/internals2.opcodes.instanceof.php Edit -- https://master.php.net/note/edit/117491 Del: integrated -- https://master.php.net/note/delete/117491/integrated Del: useless -- https://master.php.net/note/delete/117491/useless Del: bad code -- https://master.php.net/note/delete/117491/bad+code Del: spam -- https://master.php.net/note/delete/117491/spam Del: non-english -- https://master.php.net/note/delete/117491/non-english Del: in docs -- https://master.php.net/note/delete/117491/in+docs Del: other reasons-- https://master.php.net/note/delete/117491 Reject -- https://master.php.net/note/reject/117491 Search -- https://master.php.net/manage/user-notes.php
