_SESSION increment function

[Vjgyxioncm]

My function:\[code\]function SessionSet($s, $v = '') { if (is_array($s)) { foreach ($s as $k => $v) $_SESSION[$k] = $v; } else { $_SESSION[$s] = $v; }}\[/code\]It's possible make it work like this:\[code\]SessionSet('user_visits')++;\[/code\]Just a simple increment, but don't have any ideas how...
