Is there a more concise way of writing this simple PHP conditional?

It se开发者_Go百科ems like there would be a shorter way of writing this:

if ($action == 'add' || $action == 'update' || $action == 'delete') {
       // whatever
}

is there?

if (in_array($action, array('add', 'update', 'delete'))) {
    // whatever
}

I prefer this form, since it is easier to maintain:

if(in_array($action, array('add', 'update', 'delete'))) {

}
