php用header函数实现301跳转代码实例

PHP 301跳转的小代码

代码如下:

PHP
$the_host = $_SERVER['HTTP_HOST'];
$request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
if($the_host !== 'www.jb51.cc')
{
//echo $_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: . $_SERVER['PHP_SELF'] . $request_uri);
}
?>
