note 100807 added to function.empty

To make an empty function, which only accepts arrays, one can use type-hinting: // emptyArray :: [a] -> Bool function emptyArray(array $xs){ return empty($xs); } Type hinting is a good thing to use in your code, because it makes it more easy to reason about your code. Besides that, it automatically documents the code. ---- Server IP: 69.147.83.197 Probable Submitter: 178.224.17.144 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/100807 Del: integrated -- https://master.php.net/note/delete/100807/integrated Del: useless -- https://master.php.net/note/delete/100807/useless Del: bad code -- https://master.php.net/note/delete/100807/bad+code Del: spam -- https://master.php.net/note/delete/100807/spam Del: non-english -- https://master.php.net/note/delete/100807/non-english Del: in docs -- https://master.php.net/note/delete/100807/in+docs Del: other reasons-- https://master.php.net/note/delete/100807 Reject -- https://master.php.net/note/reject/100807 Search -- https://master.php.net/manage/user-notes.php
