$array[two]=2;
$array[three]=3;
$array[four]=4;
$new_array=name_sort($array);

?>
<?php
function name_sort($array, $type='asc') {
$result=array();
foreach($array as $var => $val){
$set=false;
foreach($result as $var2 => $val2){
if ($set==false) {
if ($var>$var2 && $type=='desc' || $var<$var2 && $type=='asc') {
$temp=array();
foreach($result as $var3 => $val3){
