Automatic Switching

    I like to use a php function to switch between ON and OFF automatically upon the call.
    Of course something simple like

    $condition="OFF";
    switch ($condition) {
    case "OFF" :
    $condition="ON";
    break;
    case "ON" :
    $condition="OFF";
    break;
    }

    this always returns ON but that is not what I need. How can I make it so that it remember the previous setting of $condition and act accordingly so it alternate between ON/Off automatically upon the call to the function?

    Thanks

    Maybe you can store the last value (ON or OFF) in a session variable.

    
session_start();

$_SESSION['last_state'] = 'OFF';

switch ($_SESSION['last_state']) {
case "OFF" :
$_SESSION['last_state']="ON";
break;
case "ON" :
$_SESSION['last_state']="OFF";
break;
}

    GOD O GOD Why SWITCH FOR ONLY 2 PARAMETERS?

    $_SESSION['last_state'] = ($_SESSION['last_state'] == 'OFF') ? 'ON' : 'OFF';
