使用雄辩的模型

$user = new Report();        
$user->email= 'johndoe@example.com';  
$user->save();
$lastId = $user->id;

使用查询生成器

$lastId = DB::table('reports')->insertGetId(['email' => 'johndoe@example.com']);

下面是我们如何在Laravel 4中获得最后一个插入id

public function store()
{
    $input = Input::all();

    $validation = Validator::make($input, user::$rules);

    if ($validation->passes())
    {

     $user= $this->user->create(array(
            'name'              => Input::get('name'),
            'email'             => Input::get('email'),
            'password'          => Hash::make(Input::get('password')),
        ));
        $lastInsertedId= $user->id; //get last inserted record's user id value
        $userId= array('user_id'=>$lastInsertedId); //put this value equal to datatable column name where it will be saved
        $user->update($userId); //update newly created record by storing the value of last inserted id
            return Redirect::route('users.index');
        }
    return Redirect::route('users.create')->withInput()->withErrors($validation)->with('message', 'There were validation errors.');
    }

在laravel 5中:你可以这样做:

use App\Http\Requests\UserStoreRequest;
class UserController extends Controller {
    private $user;
    public function  __construct( User $user )
    {
        $this->user = $user;
    }
    public function store( UserStoreRequest $request )
    {
       $user= $this->user->create([
            'name'              => $request['name'],
            'email'             => $request['email'],
            'password'          => Hash::make($request['password'])
        ]);
        $lastInsertedId= $user->id;
    }
}

可选方法为:

$lastID = DB::table('EXAMPLE-TABLE')
                ->orderBy('id', 'desc')
                ->first();

$lastId = $lastProduct->id;

来自Laravel 5.8版本

虽然这个问题有点过时了。我的快速解决方案是这样的:

$last_entry = Model::latest()->first();

但我猜它很容易受到频繁使用的数据库的竞争条件的影响。

获取数据库中最后插入的id 你可以使用

$data = new YourModelName;
$data->name = 'Some Value';
$data->email = 'abc@mail.com';
$data->save();
$lastInsertedId = $data->id;

这里$lastInsertedId会给你最后插入的自动增量id。
