I recently started building my own version of a semi-transparent mirror info panel. The server inside is running as a main service station for basically everything.
The server is hosting an external hard disk to serve videos, music and hard disk space via minidlna, nfs, appletalk and samba. Further the server is hosting my mail, imap, icinga, etc services.
A web front end is showing the basic information on an LCD behind the semi-transparent screen and here comes the PHP behind:
<?php ############# HEAD ############################
$refresh_period = "3600";# refresh once in an hour only
$PHP_SELF = htmlspecialchars($_SERVER['PHP_SELF']); # use one file only which will be reload with new parameters all the time
header("Refresh: $refresh_period; url=$PHP_SELF");
echo "<!DOCTYPE html>\n";
echo "<html>\n<head>\n <meta http-equiv='refresh' content='.".$refresh_period."'><meta charset='utf-8'><meta name='viewport' content='width=device-width, initial-scale=1.0'>\n";
require_once('simpleCalDAV/SimpleCalDAVClient.php');
$client = new SimpleCalDAVClient();
