Note Submitter: hillar dot petersen at gmail dot com ---- In addition to my previous post. If your values are already in utf-8 maybe you want to utf8_encode array keys only. This will do it: <?php /** * (Recursively) utf8_encode all array keys. * * @param array $array * @return array with utf8_encoded keys */ function utf8_encode_array_keys($array) { $array_type = array_type($array); if ($array_type == "map") { $result_array = array(); foreach($array as $key => $value) { if (is_array($value)) { // recursion $result_array[utf8_encode($key)] = utf8_encode_array_keys($value); } else { // value is not an array, no recursion $result_array[utf8_encode($key)] = $value; } } return $result_array; } else if ($array_type == "vector") { // do not encode anything, just follow the value if it is an array $result_array = array(); foreach ($array as $key => $value) { if (is_array($value)) { // recursion $result_array[$key] = utf8_encode_array_keys($value); } else { // value is not an array, no recursion $result_array[$key] = $value; } } return $result_array; } return false; // argument is not an array, return false } ?> Also note that both this operation (with keys only) and the operation with both keys and values can be reversed by replacing "encode" by "decode".
