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 $fillable attribute defines fields that can be batch assigned.
- View (View)
The view layer is the part of the Laravel application responsible for user interface display. In the MVC architecture, the view layer is responsible for presenting data from the model layer to users. In Laravel, views are typically rendered using the Blade template engine.
The following is a simple view example, showing the user list interface:
<!DOCTYPE html>
<html>
<head>
<title>User List</title>
</head>
<body>
<h1>User List</h1>
<ul>
@foreach($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.

How to set environment variables in PHP environment Description of adding PHP running environment variables
Jul 25, 2025 pm 08:33 PM
There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en
How to make PHP container support automatic construction? Continuously integrated CI configuration method of PHP environment
Jul 25, 2025 pm 08:54 PM
To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction
What is Configuration Caching in Laravel?
Jul 27, 2025 am 03:54 AM
Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.
Explain Laravel Eloquent Scopes.
Jul 26, 2025 am 07:22 AM
Laravel's EloquentScopes is a tool that encapsulates common query logic, divided into local scope and global scope. 1. The local scope is defined with a method starting with scope and needs to be called explicitly, such as Post::published(); 2. The global scope is automatically applied to all queries, often used for soft deletion or multi-tenant systems, and the Scope interface needs to be implemented and registered in the model; 3. The scope can be equipped with parameters, such as filtering articles by year or month, and corresponding parameters are passed in when calling; 4. Pay attention to naming specifications, chain calls, temporary disabling and combination expansion when using to improve code clarity and reusability.

How to build a log management system with PHP PHP log collection and analysis tool
Jul 25, 2025 pm 08:48 PM
Select logging method: In the early stage, you can use the built-in error_log() for PHP. After the project is expanded, be sure to switch to mature libraries such as Monolog, support multiple handlers and log levels, and ensure that the log contains timestamps, levels, file line numbers and error details; 2. Design storage structure: A small amount of logs can be stored in files, and if there is a large number of logs, select a database if there is a large number of analysis. Use MySQL/PostgreSQL to structured data. Elasticsearch Kibana is recommended for semi-structured/unstructured. At the same time, it is formulated for backup and regular cleaning strategies; 3. Development and analysis interface: It should have search, filtering, aggregation, and visualization functions. It can be directly integrated into Kibana, or use the PHP framework chart library to develop self-development, focusing on the simplicity and ease of interface.
