Bellow I put some example to doing that and the results. regards, Luis Test script: --------------- <?php function arrKey2Lower(&$arrVals) { foreach( $arrVals as $key => $item ) { $key2 = strtolower($key); if ( $key2 != $key) { unset($arrVals[$key]); $arrVals[$key2]=$item; $key=$key2; } if ( is_array($item) ) { arrKey2Lower($arrValores[$key]); } } } $arr = array('ID' => 1, 'NAME'=> 'Luis', 'Contact' => array('PHONE' => '3010-7148', 'E-MAIL' => 'luis@net.com') ); arrKey2Lower($arr); var_dump($arr); ?> Expected result: ---------------- array(3) { ["id"]=> int(1) ["name"]=> string(4) "Luis" ["contact"]=> array(2) { ["phone"]=> string(9) "3010-7148" ["e-mail"]=> string(12) "luis@net.com" } } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52917&edit=1
