There may be times when you want a specific page (URL) to automatically redirect to a different page before loading. To do so, place the following at the very top of the coded page, before anything else on the page.

This would be used for a temporary redirect.

// redirect the user
header('Location: http://example.com/newpage.html');

// make sure all code below does not get executed
exit;

To perform a permanent redirect (status code 301), you can use the following.

// redirect the user
header('Location: http://example.com/newpage.html', true, 301);

// make sure all code below does not get executed
exit;
