Laravel insert ignore check if inserted (affected rows for insert ignore)

Halo guys!
if you break your head for finding solution to check if row is inserted here is the way

$query = "INSERT INTO table (id) VALUES (?)";
    try {
        DB::insert($query, array($value));
        return 1;
    } catch (\Exception $e) {
        return 0;
    }

The solution is simle - not use insert ignore. So we are catching exception instead of fatal erroring and know if it did or not.
You can even do query builder insert instead of raw query.
