In Laravel, you can use the new keyword in PHP to instantiate objects. For example, if you want to instantiate a model object named User, you can do so like this:

$user = new User();

To pass parameters to an object’s constructor, you can do so by using parentheses after the new keyword, for example:

$user = new User(['name' => 'John Doe', 'email' => 'john@example.com']);

Additionally, in Laravel, you can also use dependency injection to instantiate objects. Laravel’s service container can automatically resolve dependencies of objects and instantiate the required objects. For example, you can instantiate a service in a controller like this:

public function index(UserService $userService)
{
    // 使用 $userService 对象
}

In this example, Laravel will automatically instantiate a UserService object and inject it into the index method.
