How to use a PHP redirection to redirect url to a new page

Redirection from one web page to another is a handy tool. This recipe describes the syntax that causes the client to redirect to another URL.

The following php script redirects the user to /index.php within the same site:

<? header('Location: /index.php'); ?>

The redirection target can be any suitable URL as could be used in the href parameter of an address tag (such as http://www.tech-recipes.com/index.php). The header function sends raw header data to the client web browser and in this case sends a 302 status code which instructs the browser to redirect to the given location.
