Sometimes you just need to mask a script or reject a user from a page this can be done effortlessly using a single line of code. Header location will allow you to redirect a user quickly and without them having any control over the action.

A good example of this forced redirection is an “if” statement. Here is a simple if statement using the header location. If the users ip addres = ’192.167.3.2’ then they will be redirected to the wanted page, else they will be rejected and taken to another page such as a 401 or 403

if ($ip_address==’192.167.3.2’){ header('Location: http://www.example.com/allow_in.php');
}
else
{
header('Location: http://www.example.com/ deny_acces.php ');
}
