note 82256 added to function.array-map

Wish this was built in. Mimics Ruby and Prototype's array pluck function. Returns specific key/column from an array of objects. <?php function array_pluck($key, $array) { if (is_array($key) || !is_array($array)) return array(); $funct = create_function('$e', 'return is_array($e) && array_key_exists("'.$key.'",$e) ? $e["'. $key .'"] : null;'); return array_map($funct, $array); } // usage: $a = array(array("id"=>10, "name"=>"joe"), array("id"=>11, "name"=>"bob")); $ids = array_pluck("id", $a); // == array(10,11) $names = array_pluck("name", $a); // == array("joe", "bob") //works on non-keyed arrays also: $a = array(array(3,4), array(5,6)); $col2 = array_pluck(1,$a); // == array(4,6) (grab 2nd column of data) ?> ---- Server IP: 209.41.74.194 Probable Submitter: 64.81.48.166 ---- Manual Page -- http://www.php.net/manual/en/function.array-map.php Edit -- https://master.php.net/note/edit/82256 Del: integrated -- https://master.php.net/note/delete/82256/integrated Del: useless -- https://master.php.net/note/delete/82256/useless Del: bad code -- https://master.php.net/note/delete/82256/bad+code Del: spam -- https://master.php.net/note/delete/82256/spam Del: non-english -- https://master.php.net/note/delete/82256/non-english Del: in docs -- https://master.php.net/note/delete/82256/in+docs Del: other reasons-- https://master.php.net/note/delete/82256 Reject -- https://master.php.net/note/reject/82256 Search -- https://master.php.net/manage/user-notes.php
