php把所有页面都指一个域名301永久转向代码

$url = "http://".$url.$_server["request_uri"];
header("http/1.1 301 moved permanently");
header ("location:http://$url");

$url = 'aaa.php?region='.urldecode("四川省");

?>
<a href="<?php echo $url;?>">aaa </a>

//方法二base64_encode

<?
$test="四川省";
$test1=base64_encode($test);
echo '<a href="www.111cn.net?region=$test1">aaa </a>';
?>

另一页面使用base64_decode解开

base64_decode($region);

//方法三让服务器支持中文
