// import the necessary class use App\Models\User; // retrieve a user by ID $user = User::findById(1); // access user properties echo $user->name; echo $user->email;This code example assumes that you have a User model with a static findById method that takes an ID as a parameter and returns a User instance. It's likely that this package and library is related to a PHP framework such as Laravel, which is why you are calling the static method with the double colons.
