note 130188 added to functions.first_class_callable_syntax

Also note that closures are not serializable. So if you are storing a reference to a callback in a variable that will be serialized for caching or any other purpose, do not switch to this syntax or your serialization will break. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.84.18 (proxied: 38.66.96.75) ---- Manual Page -- https://php.net/manual/en/functions.first_class_callable_syntax.php Edit -- https://main.php.net/note/edit/130188 Del: integrated -- https://main.php.net/note/delete/130188/integrated Del: useless -- https://main.php.net/note/delete/130188/useless Del: bad code -- https://main.php.net/note/delete/130188/bad+code Del: spam -- https://main.php.net/note/delete/130188/spam Del: non-english -- https://main.php.net/note/delete/130188/non-english Del: in docs -- https://main.php.net/note/delete/130188/in+docs Del: other reasons-- https://main.php.net/note/delete/130188 Reject -- https://main.php.net/note/reject/130188 Search -- https://main.php.net/manage/user-notes.php
