PHP Implementation 301 REDIRECT Jump instance Code _php instance

In PHP 301 REDIRECT implementation is very simple, we simply use the header to send 301 status code, and then use header to jump, the effect and Apache,iis,nginx are the same effect oh.

One: This method is more recommended because it can transfer all the URLs of Http://www.jb51.net to Http://jb51.net's new address.

The code is as follows

<?php
$the _host = $_server[' http_host '];
$request _uri = isset ($_server[' Request_uri '))? $_server[' Request_uri ']: ';
if ($the _host = = ' Www.jb51.net ')
{
header (' http/1.1 moved Permanently ');
Header (' location:http://jb51.net '. $request _uri);/
}
?>

Second: Single-page multi-station Php301 redirection code , www.jb51.net and jb51.net 301 to index.php,jbzj.com 301 to Www.jbzj.com , otherwise go to error page

The code is as follows

if ($HTTP _host== "www.jb51.net") or ($HTTP _host== "jb51.net"))
{
header ("http/1.1-Moved Permanently");
Header ("Location:/index.php");
}
ElseIf ($HTTP _host== "jbzj.com")
{
header ("http/1.1-Moved Permanently");
Header ("Location:www.jbzj.com");
}
else
{
Header ("Location:/404.htm");
>
