Laravel's model-view-controller (MVC) architecture analysis
Laravel’s Model-View-Controller (MVC) Architecture Analysis
MVC (Model-View-Controller) is an architecture widely used in software development model. The Laravel framework also adopts the MVC architecture. Its core concept is to divide the application into three layers: Model, View and Controller. They work together through their respective responsibilities to achieve high cohesion of the code. and low coupling, making applications easier to maintain and expand.
Below we will delve into the MVC architecture in Laravel and understand its implementation through sample code.
- Model
The model layer is the part of the Laravel application responsible for processing data. Typically, the model layer contains business logic that interacts with data and operations that interact with the database. In Laravel, the model inherits from the Eloquent class. Eloquent is Laravel's ORM (Object Relational Mapping) system, through which we can easily operate the database.
The following is a simple user model example, assuming that our application needs a user table to store user information:
<?php
namespace AppModels;
use IlluminateDatabaseEloquentModel;
class User extends Model
{
protected $table = 'users';
protected $fillable = ['name', 'email', 'password'];
}In the above code, we created a User model, Inherited from the IlluminateDatabaseEloquentModel class. The $table attribute specifies the corresponding database table name, and the $fillable attribute defines fields that can be batch assigned.
- View (View)
The view layer is the part of the Laravel application responsible for user interface display. In the MVC architecture, the view layer is responsible for presenting data from the model layer to users. In Laravel, views are typically rendered using the Blade template engine.
The following is a simple view example, showing the user list interface:
<!DOCTYPE html>
<html>
<head>
<title>User List</title>
</head>
<body>
<h1 id="User-List">User List</h1>
<ul>
@foreach($users as $user)
<li>{{ $user->name }}</li>
@endforeach
</ul>
</body>
</html>In the above code, we use the syntax of the Blade template engine. {{ $user->name }} means outputting the name field of the $user model.
- Controller (Controller)
The controller layer is the part of the Laravel application that is responsible for processing user requests and controlling business logic. In Laravel, a controller is usually a class that contains multiple action methods.
The following is a simple controller example for handling requests for user lists:
<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use AppModelsUser;
class UserController extends Controller
{
public function index()
{
$users = User::all();
return view('user.list', ['users' => $users]);
}
}In the above code, we created a UserController controller class, in which the index method Used to handle requests for user lists. In the index method, we use the all method of the User model to obtain all user data, and return the user.list view through the view method, passing an array parameter named users.
Finally, we need to associate the request with the controller method in the routing:
Route::get('/users', 'AppHttpControllersUserController@index');In the above code, when the /users path is accessed, the index method of UserController will be called.
Through the above sample code, we can see the specific implementation of Laravel's MVC architecture. The model layer is responsible for interacting with the database, the view layer displays data to users, and the controller layer handles user requests and schedules business logic. This layered approach makes the application code clearer, more concise, and easier to maintain.
Summary:
Through the above analysis of Laravel's MVC architecture, we have learned about the model-view-controller layered architecture pattern. The advantage of the MVC architecture is the high cohesion and low coupling of the code, making application development more efficient and scalable. At the same time, the Laravel framework provides us with powerful tools and conventions, allowing us to implement the MVC architecture more conveniently.
I hope that the introduction of this article can give readers a deeper understanding of Laravel's MVC architecture and enable it to be better used in practical applications.

Laravel Eloquent ORM in Bangla partial model search)
Apr 08, 2025 pm 02:06 PM
LaravelEloquent Model Retrieval: Easily obtaining database data EloquentORM provides a concise and easy-to-understand way to operate the database. This article will introduce various Eloquent model search techniques in detail to help you obtain data from the database efficiently. 1. Get all records. Use the all() method to get all records in the database table: useApp\Models\Post;$posts=Post::all(); This will return a collection. You can access data using foreach loop or other collection methods: foreach($postsas$post){echo$post->
Linux Architecture: Unveiling the 5 Basic Components
Apr 20, 2025 am 12:04 AM
The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.
Solve caching issues in Craft CMS: Using wiejeben/craft-laravel-mix plug-in
Apr 18, 2025 am 09:24 AM
When developing websites using CraftCMS, you often encounter resource file caching problems, especially when you frequently update CSS and JavaScript files, old versions of files may still be cached by the browser, causing users to not see the latest changes in time. This problem not only affects the user experience, but also increases the difficulty of development and debugging. Recently, I encountered similar troubles in my project, and after some exploration, I found the plugin wiejeben/craft-laravel-mix, which perfectly solved my caching problem.
Laravel user login function
Apr 18, 2025 pm 12:48 PM
Laravel provides a comprehensive Auth framework for implementing user login functions, including: Defining user models (Eloquent model), creating login forms (Blade template engine), writing login controllers (inheriting Auth\LoginController), verifying login requests (Auth::attempt) Redirecting after login is successful (redirect) considering security factors: hash passwords, anti-CSRF protection, rate limiting and security headers. In addition, the Auth framework also provides functions such as resetting passwords, registering and verifying emails. For details, please refer to the Laravel documentation: https://laravel.com/doc
Laravel's geospatial: Optimization of interactive maps and large amounts of data
Apr 08, 2025 pm 12:24 PM
Efficiently process 7 million records and create interactive maps with geospatial technology. This article explores how to efficiently process over 7 million records using Laravel and MySQL and convert them into interactive map visualizations. Initial challenge project requirements: Extract valuable insights using 7 million records in MySQL database. Many people first consider programming languages, but ignore the database itself: Can it meet the needs? Is data migration or structural adjustment required? Can MySQL withstand such a large data load? Preliminary analysis: Key filters and properties need to be identified. After analysis, it was found that only a few attributes were related to the solution. We verified the feasibility of the filter and set some restrictions to optimize the search.

Apr 11, 2025 am 11:29 AM
How does Laravel play a role in backend logic? It simplifies and enhances backend development through routing systems, EloquentORM, authentication and authorization, event and listeners, and performance optimization. 1. The routing system allows the definition of URL structure and request processing logic. 2.EloquentORM simplifies database interaction. 3. The authentication and authorization system is convenient for user management. 4. The event and listener implement loosely coupled code structure. 5. Performance optimization improves application efficiency through caching and queueing.
