note 114970 added to function.array-map

Here is an example for php 5.4 and greater, using a closure: <?php $myList = [1,2,3,4]; $mappedList = array_map(function($value){ return $value * 2; }, $myList); var_dump($mappedList); array(4) { [0]=>int(2) [1]=>int(4) [2]=>int(6) [3]=>int(8) } ?> This is useful when you don't want/need to define a function just so it can be used with the map function. ---- Server IP: 72.52.91.14 Probable Submitter: 71.252.134.63 ---- Manual Page -- http://php.net/manual/en/function.array-map.php Edit -- https://master.php.net/note/edit/114970 Del: integrated -- https://master.php.net/note/delete/114970/integrated Del: useless -- https://master.php.net/note/delete/114970/useless Del: bad code -- https://master.php.net/note/delete/114970/bad+code Del: spam -- https://master.php.net/note/delete/114970/spam Del: non-english -- https://master.php.net/note/delete/114970/non-english Del: in docs -- https://master.php.net/note/delete/114970/in+docs Del: other reasons-- https://master.php.net/note/delete/114970 Reject -- https://master.php.net/note/reject/114970 Search -- https://master.php.net/manage/user-notes.php
