Php programming
Use the PHP
header()FunctionYou can simply use the PHP
header()function to redirect a user to a different page.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.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.
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.
