Laravel只从数据库中获取一个没有stdClass对象的值

Question

Hello people here is my code below...

        $uid = DB::table('users')
                     ->where('email', '=', Input::get('email'))
                     ->select('email')
                     ->get();

                    print_R ($uid);

this will output Array ( [0] => stdClass Object ( [email] => [e-mail] ) ) I want only [email] => [e-mail] so that i can save in session, Without using foreach loop can we get an outfput [0] => stdClass Object ????

If you are using Laravel 4, there is a great helper that does just what you need. Here is the update code for your example :

$uid = DB::table('users')
        ->where('email', '=', Input::get('email'))
        ->pluck('email');

As for laravel3 the docs state that upper example changes to :

$uid = DB::table('users')
        ->where('email', '=', Input::get('email'))
        ->only('email');
