多个页面之间的循环（刷新）？

I have a set of pages with the following names....

  • update1.php
  • update2.php
  • update3.php
  • update4.php
  • update5.php
  • update6.php
  • update7.php

At the moment, I have all 7 open on Chrome and refreshing every 30 minutes using the following code.

<body onload="setInterval('window.location.reload()', 1800000);">

I want to stick all these pages together so that I need only 1 page open. Is there a way to make a page refresh every 5 mins, but load a different section each time?

I was thinking of doing something like this, but it seems a bad way of doing it...

$refresh = $_GET['refresh'];

if (!isset($refresh)) { //update1 stuff; //reload page with &refresh=2 }
elseif ($refresh == 1) { //update1 stuff; //reload page with &refresh=2 }
elseif ($refresh == 2) { //update2 stuff; //reload page with &refresh=3 }    
elseif etc.....

Any ideas?

    In your php code that outputs the page html code, try something like this:

    <?php echo ($_GET['refresh'] % 7) + 1; ?>.php // Name of next page

?refresh=<?php echo ($_GET['refresh'] % 7) + 1; ?>"; // Name of next page + 1

// All together
<body onload="setTimeout(function() { window.location.href = 'update<?php echo ($_GET['refresh'] % 7) + 1; ?>.php?refresh=<?php echo ($_GET['refresh'] % 7) + 1; ?>';}, 1800000);">

    This will open the new page with an incremented number after the specified time interval. The modulo operation helps us run through the pages in a consistent loop.
