How do I redirect to another page after 5 minutes using PHP?
With just HTML:
<meta http-equiv="refresh" content="300;http://redirect-url" />
This will redirect to http://redirect-url
after 300 seconds (5 minutes).
Javascript's setTimeout() is probably what you want. An example would be:
setTimeout(function(){ window.location = "<URL HERE>";}, 5*60*1000);
window.location is what you can use in javascript to set the current location of the window. Something to consider, however, is that most browsers do not let you set window.location without some type of user input before hand, such as a click.

If you really want to use PHP for this, here you go:
<?php header("Refresh: 300; URL=http://www.stackoverflow.com/"); ?>
