Hi i wonder how i can check if user is online or not, when i login user i put time() in database. This stores ip in other table, but what if user browser crash ? He will still be online. ( BTW i found this tutorial on some page its not mine code. ) So what i need to show me if user is online or not. So if user dont do nothing on any page on website or crash after lets say 5 min show him like offline. Thanks in advance. <?php //server info here $server = "localhost"; $db_user = "root"; $db_pass = ""; $database = "test"; $timeoutseconds = 300; //this is where PHP gets the time $timestamp = time(); $timeout = $timestamp - $timeoutseconds; $mysqli = new mysqli($server, $db_user, $db_pass, $database); //insert the values $insert = "INSERT INTO useronline VALUES (?, ?, ?)"; $stmt = $mysqli->prepare( $insert ); $stmt->bind_param( 'iss', $timestamp, $_SERVER['REMOTE_ADDR'],$_SERVER['PHP_SELF'] ); if(!$stmt->execute()) { print "Useronline Insert Failed > "; } //delete values when they leave $delete = "DELETE FROM useronline WHERE timestamp < ?"; $stmt = $mysqli->prepare( $delete ); $stmt->bind_param( 'i', $timeout ); if(!$stmt->execute()) { print "Useronline Delete Failed > "; } //grab the results $result = "SELECT DISTINCT ip FROM useronline WHERE file = ?"; $stmt = $mysqli->prepare( $result ); $stmt->bind_param( 's', $_SERVER['PHP_SELF'] ); if(!$stmt->execute()) { print "Useronline Select Error > "; } //number of rows = the number of people online $user = $stmt->num_rows; //spit out the results $mysqli->close(); if($user == 1) { print("$user user online\n"); } else { print("$user users online\n"); } ?>
