If you want to make sure that one of the parameters of your function is a Closure, you can use Type Hinting. see: http://php.net/manual/en/language.oop5.typehinting.php Example: <?php class TheRoot { public function poidh($param) { echo "TheRoot $param!"; } } class Internet { # here, $my_closure must be of type object Closure public function run_my_closure($bar, Closure $my_closure) { $my_closure($bar); } } $Internet = new Internet(); $Root = new TheRoot(); $Internet->run_my_closure($Root, function($Object) { $Object->poidh(42); }); ?> The above code simply yields: "TheRoot 42!" NOTE: If you are using namespaces, make sure you give a fully qualified namespace. print_r() of Internet::run_my_closure's $my_closure <?php Closure Object ( [parameter] => Array ( [$Object] => ) ) ?> var_dump() of Internet::run_my_closure's $my_closure <?php object(Closure)#3 (1) { ["parameter"]=> array(1) { ["$Object"]=> string(10) "" } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 112.135.166.126 ---- Manual Page -- http://www.php.net/manual/en/functions.anonymous.php Edit -- https://master.php.net/note/edit/96755 Del: integrated -- https://master.php.net/note/delete/96755/integrated Del: useless -- https://master.php.net/note/delete/96755/useless Del: bad code -- https://master.php.net/note/delete/96755/bad+code Del: spam -- https://master.php.net/note/delete/96755/spam Del: non-english -- https://master.php.net/note/delete/96755/non-english Del: in docs -- https://master.php.net/note/delete/96755/in+docs Del: other reasons-- https://master.php.net/note/delete/96755 Reject -- https://master.php.net/note/reject/96755 Search -- https://master.php.net/manage/user-notes.php
