how to load each php file for 5 mins then move to the next one?

I have 5 PHP files, (1.php,2.php,3.php,4.php,5.php) how can I load 1.php for 5 mins, then load 2.php for 5 mins then again 1.php after that 3.php in a specific order.

I have tried it with a button but I want it to do that without buttons just 5 mins then move on
