note 93791 added to function.call-user-func

PHP 5.3 is prone to black magic. Now, you can do this: $arr = array(1,2); isset($arr) && is_array($arr) && sizeof($arr) > 0 && call_user_func(function() use ($arr) {foreach($arr as $a){print_r($a);}}); It's valid, it'll work. Should you do it? No. ---- Server IP: 187.16.23.128 Probable Submitter: 187.37.26.30 ---- Manual Page -- http://www.php.net/manual/en/function.call-user-func.php Edit -- https://master.php.net/note/edit/93791 Del: integrated -- https://master.php.net/note/delete/93791/integrated Del: useless -- https://master.php.net/note/delete/93791/useless Del: bad code -- https://master.php.net/note/delete/93791/bad+code Del: spam -- https://master.php.net/note/delete/93791/spam Del: non-english -- https://master.php.net/note/delete/93791/non-english Del: in docs -- https://master.php.net/note/delete/93791/in+docs Del: other reasons-- https://master.php.net/note/delete/93791 Reject -- https://master.php.net/note/reject/93791 Search -- https://master.php.net/manage/user-notes.php
