OnlineUsers class

"20 users online" style user tracking is (was) a favourite of ASP websites - this class allows you to do the same thing easily in PHP. The OnlineUsers class uses a leightweight mySQL table to track the users, logging them to a table. Details of who is online and how many users is then easily retrieved. This latest version features an optimised database structure and calls to the database.

This class like all PHP classes on sloppycode.net was made in PHP 3.x or 4, so unfortunately isn't guaranteed to be error free anymore.

<?
// Use this example on every page you want to track people
require("clsOnlineUsers.php");
$users = new OnlineUsers();

// The update frequency is how often the table is flushed of out of date
// users. The default is 5, in the case below the user would have a 1 in
// 3 chance of triggering the flush table function, when they request a page
$user->update_frequency = 3;

$users->host     = "localhost";
$users->username = "username";
$users->password = "password";
$users->dbname   = "usersonline";
$users->tablename = "users_online";
$users->timeout = 5;
$users->dbconnect();
$users->updateAddUser();
echo $users->getUsersOnline(). " user(s) online";

// Use this example for gettting detailed information about who is online,
// and for setting up the database/table if necessary
$users = new OnlineUsers();
$users->updateAddUser();
$users->host     = "localhost";
$users->username = "username";
$users->password = "password";
$users->dbname   = "usersonline";
$users->tablename = "users_online";
$users->timeout = 5;
$users->dbconnect();

// Setup table/db if not already setup. 
// Make sure to set dbname/tablename before calling this method
// $users->setup(true,);

// Get detailed log
$contents = $users->openTemplate("template.html");
echo $users->showFullInfo(true,$contents)
?>
