user online errore

[mariox]

prova così:

$server = "localhost";
$db_user = "root";
$db_pass = "";
$database = "3333";
$timeoutseconds = 300;

$timestamp = time();
$timeout = $timestamp-$timeoutseconds;

$REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
$PHP_SELF = $_SERVER['PHP_SELF'];

mysql_connect($server, $db_user, $db_pass);
$insert = mysql_db_query($database, "INSERT INTO useronline VALUES ('$timestamp','$REMOTE_ADDR','$PHP_SELF')");

if(!($insert)) {
print "Useronline Insert Failed > ";
}

$delete = mysql_db_query($database, "DELETE FROM useronline WHERE timestamp<$timeout");

if(!($delete)) {
print "Useronline Delete Failed > ";
}

$result = mysql_db_query($database, "SELECT DISTINCT ip FROM useronline WHERE file='$PHP_SELF'");

if(!($result)) {
print "Useronline Select Error > ";
}

$user = mysql_num_rows($result);

mysql_close();

if($user == 1) {
print("[b]$user[/b] user onlinen");
} else {
print("[b]$user[/b] users onlinen");
}
