How can I redirect web site visitors using PHP?
You can use the PHP header() function to redirect a user to a different page in a simple, efficient manner.
The PHP code in the following example will redirect the user from the page in which it is placed to the URL http://www.example.com/another-page.php. You can also specify relative URLs.
<?php header("Location: http://www.example.com/another-page.php"); exit(); ?>
If you want to redirect the users from old page to a new page on a permanent basis then also mention HTTP response code in the header() function as shown in the following example, so that search engines transfer "page rank" from the old page to the new page.
<?php // 301 Moved Permanently header("Location: http://www.example.com/another-page.php", true, 301); exit(); ?>
If the status code is not specified explicitly, for instance header("Location: URL") defaults to 302 (Found). For temporary redirect use the HTTP status code 307.
