    return DB::table('graphs')->groupBy('title')->get();
}

I kept getting

Can someone please help ?

I expected to get these 3

Answer 1

In MySql strict mode, you can't return non aggregated fields in a group by query. If you need only the title's values add a select or a pluck method

public function types()
{
    return DB::table('graphs')->groupBy('title')->pluck('title')->toArray();
}

Answer 2

Try orderBy() instead of groupBy().

public function types()
{
    return DB::table('graphs')->orderBy('title')->get();
}
