What is a more elegant solution to these nested if/elseif statements?

Question

I\'m building a website that contains users with user profiles. Many of the fields in the profile are optional.

There is an opportunity for a lot of user-generate

I'm not sure that my version would be simplier, but here it is:

public function nameify($names = null) {
    $result = array();

    if( !empty($names['display_name']) ) {
        array_push($result,$names['display_name']);
    } else {
        if( !empty($names['first_name']) ) {
            array_push($result, $names['first_name']);
        }
        if( !empty($names['last_name']) ) {
            array_push($result, $names['last_name']);
        }
    }

    if( empty($result) && !empty($names['id']) ) {
        array_push($result, 'user'.$names['id']);
    }

    return (empty($result) ? 'NULL' : implode(' ', $result));
}
