Question

My function:

function SessionSet($s, $v = '') {
    if (is_array($s)) {
        foreach ($s as $k => $v) $_SESSION[$k] = $v;
    } else {
        $_SESSION[$s] = $v;
    }
}

It’s possible make it work like this:

SessionSet('user_visits')++;

Just a simple increment, but don’t have any ideas how…

Answer 1

How about

$_SESSION['user_visits']++;

instead?

You cannot increment the return value of a function – there’s nowhere for the incremented value to be stored.
