I need a php script that will count the number of people on my website at that particular moment in time.  I dont want the scripts to use a mysql database i want it to use flat text files.  

so for example......
all i need to do is add this to every webpage of mine
<?php include "livecounter.php"; ?>

and
<?php include "show_livecounter.php"; ?>

With PHP, there is a much simpler way to calculate the number of users online at the same time: simply count the number of session files.

<?

session_start();

/**
 * Calculate the number of users online by
 * counting the number of session files. Returns the
 * number of users on success, or -1 on failure.
 */
function getUsersOnline() {
    $count = 0;

    $handle = opendir(session_save_path());
    if ($handle == false) return -1;

    while (($file = readdir($handle)) != false) {
        if (ereg("^sess", $file)) $count++;
    }
    closedir($handle);

    return $count;
}

echo "users online = " . getUsersOnline() . "<br>";

?>
tUsersOnline() . "<br>";

?>
