There are two main PHP-centric solutions to this. First is cookies (as
you described) and the second is using the $_SESSION global array.
Doing this is relatively straightforward, so if it's not working for
you, I see two possibilities: 1) You're not actually doing it right. 2)
The users isn't pressing the "Reload" button after selecting the
stylesheet. (My experience has been that simply redisplaying a page will
not clear the cached CSS styles for that page. You must hit the "Reload"
button. In fact, in some cases, like offices with caching webservers or
proxies, an admin will have to be called in to clear the cache on the
proxy/server as well.)
You should be able to do something like this (I'm using SESSION
// Top of page
if ($_SESSION['stylesheet'] == 'enlarged_print')
$css = 'enlarged_print.css';
<link href="<?php echo $css; ?>" rel="stylesheet" type="text/css"/>
