    $_SESSION['countdown'] = 120;
    //Store the timestamp of when the countdown began.
    $_SESSION['time_started'] = time();

//Get the current timestamp.
$now = time();

//Calculate how many seconds have passed since
//the countdown began.
$timeSince = $now - $_SESSION['time_started'];

//How many seconds are remaining?
$remainingSeconds = abs($_SESSION['countdown'] - $timeSince);

//Print out the countdown.
