Online script

Auteur: leendert - 07 augustus 2005 - 17:58 - Gekeurd door: Joel - Hits: 4981 - Aantal punten: (0 stemmen)

Een script waarmee je kan zien hoeveel gasten/leden er online zijn. Ook is te zien welke leden er online zijn:

Dit is de tabel:

CREATE TABLE `online` (
`ip` varchar(20) NOT NULL default '',
`locatie` varchar(255) NOT NULL default '',
`tijd` varchar(30) NOT NULL default '',
`user_id` int(10) NOT NULL default '0',
`username` varchar(255) NOT NULL default ''
) TYPE=MyISAM;

Voor meer info zie code.

##
Dit script maakt gebruik van sessies
