Simple function to change multidimensional array's all values to uppercase. If you would like to change to lowercase then change "mb_strtoupper" to "mb_strtolower". It works perfect for me ;) <?php function change_case_recursive($arr){ foreach ($arr as $key=>$val){ if (!is_array($arr[$key])){ $arr[$key]=mb_strtoupper($arr[$key]); }else{ $arr[$key]=change_case_recursive($arr[$key]); } } return $arr; } ?> --was-- Simple function to change multidimensional array's all values to uppercase.
