The website port is not used for the time being. Generally, port 80 is used. If some websites have pages with different ports, you need to debug the port code before using it.

The Code is as follows:

Copy code

<? Php $ Dest_host = "www. Old network address. com"; // declare a variable $ dest_host to store the URL to jump $ Url = $ _ SERVER ['request _ URI ']; // declare a variable $ url to store the host address and url of the current website. $ Http = (isset ($ _ SERVER ['https']) & $ _ SERVER ['https']! = 'Off ')? 'Https: // ': 'http: //'; // declare the variable $ http storage protocol // $ Port = $ _ SERVER ['server _ port'] = '80 ′?" : '$ _ SERVER ['server _ port']; // website PORT $ Url = $ http. $ dest_host. $ url; // merged address Switch ($ _ SERVER ['HTTP _ host']) { Case "www. Website address. cn": // If the obtained host is www. Website address. cn Header ('HTTP/1.1 301 Moved Permanently '); // load 301 Header ("location:". $ url ); Break; Case "website address. cn": // or the website address. cn Header ('HTTP/1.1 301 Moved Permanently '); // load 301 Header ("location:". $ url ); Break; } ?>
