Note Submitter: moester at gmail dot com ---- 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) ?>
