Laravel, check if session array has value

How do I check, if a value already exists within a Session array? I'm trying store active tree objects within a Session array to toggle them on and off:

public function postSelected()
{
    $id = Input::get('id');
    if (Session::has('user.selection', $id)) { // check?
        Session::pull('user.selection', $id);
    } else {
        Session::push('user.selection', $id);
    }

    return Response::json(Session::get('user.selection'), 200);
}

Any ideas?

Assuming what you're trying to do is akin to a toggle (remove if present, add if missing):

$index = array_search($id, $selection = Session::get('user.selection', []));

if ($index !== false)
{
    array_splice($selection, $index, 1);
}
else
{
    $selection[] = $id;
}

Session::set('user.selection', $id);
