Note that -- as mentioned in the migration guide-- starting from PHP 8.0, is_callable() will not work with non-static methods if you use a class name, instead an object of the class should be provided: <?php class Test { public function method1() { } public static function method2() { } } // Pre PHP 8 var_dump(is_callable(array('Test', 'method1'))); // bool(true) var_dump(is_callable(array('Test', 'method2'))); // bool(true) // Post PHP 8 var_dump(is_callable(array('Test', 'method1'))); // bool(false) var_dump(is_callable(array('Test', 'method2'))); // bool(true) var_dump(is_callable(array(new Test, 'method1'))); // bool(true) ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 196.75.93.232) ---- Manual Page -- https://php.net/manual/en/function.is-callable.php Edit -- https://main.php.net/note/edit/126199 Del: integrated -- https://main.php.net/note/delete/126199/integrated Del: useless -- https://main.php.net/note/delete/126199/useless Del: bad code -- https://main.php.net/note/delete/126199/bad+code Del: spam -- https://main.php.net/note/delete/126199/spam Del: non-english -- https://main.php.net/note/delete/126199/non-english Del: in docs -- https://main.php.net/note/delete/126199/in+docs Del: other reasons-- https://main.php.net/note/delete/126199 Reject -- https://main.php.net/note/reject/126199 Search -- https://main.php.net/manage/user-notes.php
