note 129516 added to functions.anonymous

If you have a closure (or other callable) stored in an object property and you want to call it, you can use parentheses to disambiguate between it and a method call: <?php class Test { public $callable; function __construct() { $this->callable = function($a) { return $a + 2; }; } } $t = new Test; echo ($t->callable)(40); ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.13.131 (proxied: 222.152.65.7) ---- Manual Page -- https://php.net/manual/en/functions.anonymous.php Edit -- https://main.php.net/note/edit/129516 Del: integrated -- https://main.php.net/note/delete/129516/integrated Del: useless -- https://main.php.net/note/delete/129516/useless Del: bad code -- https://main.php.net/note/delete/129516/bad+code Del: spam -- https://main.php.net/note/delete/129516/spam Del: non-english -- https://main.php.net/note/delete/129516/non-english Del: in docs -- https://main.php.net/note/delete/129516/in+docs Del: other reasons-- https://main.php.net/note/delete/129516 Reject -- https://main.php.net/note/reject/129516 Search -- https://main.php.net/manage/user-notes.php
