yeah that more appropriate one thanks for that, but which one would you use?

I would do as my example here, so that would be number 2 :)

I try to follow this logic: Always filter off exception cases first, then do the intended.

So a full method would be

public function setData() 
    if (! $data)
        return;

    set_option('name', 'programming');
    set_option('age', '60');
    set_option('creater', 'Ada');
}

I generally try to avoid nested if-statements or long ones for that matter.
