Content Expiration

[Anon]

Hi, I'm brand new to PHP. I have a website, and having trouble with cached pages.. I was hoping there was a way to make the content expire everytime the site is accessed so there is no more cached pages?
Thanks,

Two things. First, go here :

http://www.php.net/manual/function.header.php

Pay close attention to the user comments too, a lot is discussed about cache and the infamous "expire" issue.

Later when you feel a little more brave, go here :

Well, to sum it up, do the following at the beginning of your scripts to prevent caching :

header("Cache-control: no-cache");
header("Pragma: no-cache");
