Architectural design based on PHP framework in large projects
Large-scale PHP projects can adopt framework-based architectural design, such as layered architecture or MVC architecture, to achieve scalability, maintainability and testability. The layered architecture includes the view layer, business logic layer, and data access layer; the MVC architecture divides the application into models, views, and controllers. The implementation framework architecture provides a modular design that makes it easy to add new features, reduce maintenance costs, and supports unit testing.
Architecture design based on PHP framework in large projects
Introduction
In When developing large-scale PHP projects, it is crucial to adopt a reasonable and consistent architectural design. This article explores how to leverage PHP frameworks to build a scalable, well-maintained code base.
Layered Architecture
Layered architecture is a common approach to breaking down an application into independent modules. For PHP projects, common layers include:
- View layer: handles the user interface and HTML output.
- Business logic layer: Contains application business logic and data operations.
- Data access layer: manages interactions with databases or other data sources.
Model-View-Controller (MVC) Architecture
MVC architecture is a popular layered pattern used specifically for web applications. It divides the application into the following components:
- Model: Represents business data and logic.
- View: Presents model data.
- Controller: Responsible for processing user requests and coordinating models and views.
Practical case: Using Laravel
Laravel is a popular PHP framework that adopts MVC architecture. The following code shows common layering in Laravel:
Model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
// 用户数据和业务逻辑
}View
<!DOCTYPE html>
<html>
<head>
<title>用户列表</title>
</head>
<body>
<table>
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
<th>电子邮件</th>
</tr>
</thead>
<tbody>
@foreach ($users as $user)
<tr>
<td>{{ $user->id }}</td>
<td>{{ $user->name }}</td>
<td>{{ $user->email }}</td>
</tr>
@endforeach
</tbody>
</table>
</body>
</html>Controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
class UserController extends Controller
{
public function index()
{
// 从模型获取数据
$users = User::all();
// 将数据传递给视图
return view('users.index', [
'users' => $users
]);
}
}Advantages
The architectural design based on the PHP framework provides the following advantages for large projects:
- Can Extensibility: Modular design makes it easier to add new features and extend the application.
- Maintainability: Layered architecture helps separate concerns and reduce code duplication.
- Testability: Modular design facilitates unit testing and integration testing.
Conclusion
Adopting a framework-based architectural design is the key to creating scalable and maintainable PHP large-scale projects. By implementing layered architectures and patterns such as MVC, developers can build robust and easy-to-maintain code bases.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
