Refreshing PHP

[crazybeans128]

I am having a problem getting the PHP on a page to be refreshed every time it comes back to the users computer. I go to the page and it just reloads what was already sitting on the computer from visiting before, so i have to refresh the page to see the new information. How come this keeps happening, and what can i do to stop it?

google "php no cache header"

from

http://us4.php.net/header:

<?php
// Date in the past
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

// always modified
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
 
// HTTP/1.1
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);

// HTTP/1.0
header("Pragma: no-cache");
?>

I'm not exactly sure what any of that means. a little bit of an explanation would be nice.

i'm telling you to google for "php no cache header", these are http headers to tell the browser not to cache the page

the example code is from the search result i referenced
