//200  Normal state 

header('HTTP/1.1 200 OK');
// 301  Permanently redirect, remember to emphasize the directed address later  Location:$url

header('HTTP/1.1 301 Moved Permanently');
//  Redirection, in fact, is 302  Temporary redirection 

header('Location: http://www.xxxx.com/');
//  Setup page 304  No modifications 

header('HTTP/1.1 304 Not Modified');
//  Displays the login box, 

header('HTTP/1.1 401 Unauthorized');

header('HTTP/1.1 500 Internal Server Error');
// 3 Redirects the specified address after seconds ( That is, refreshing to a new page is the same as  <meta http-equiv="refresh" content="10;http://www.xxxx.com/ />  Same )

echo '10 Jump back to http://www.xxxx.com';

//  Set content length 

header('Content-Length: 39344');
