We know how to retrieve  last inserted id using raw query but there are different ways to get last inserted id using Eloquent.

Here is an example:

public function saveDetailsCompany()
{
    $post = Input::All();
    $data = new Company;
    $data->name = $post['name'];
    $data->address = $post['address'];
    $data->type = $post['type'];
    $data->fecha_created = date("Y-m-d H:i:s");
    $data->fecha_modified = date("Y-m-d H:i:s");
    if ($data->save()) {
        return Response::json(array('success' => true, 'last_insert_id' => $data->id), 200);
    }
}

Another example for getting last insert id when using DB::insert is shown below.

DB::getPdo()->lastInsertId();

You can also use insertGetId method and store it in a variable and  retrieve later when needed.

$id = DB::table('users')->insertGetId([
    'email' => 'john@example.com',
    'votes' => 0
]);
