Laravel Best Practices: Building Maintainable and Scalable Applications
Introduction:
Laravel is a popular PHP framework that provides many Powerful features and tools help developers build high-quality web applications. However, to ensure the maintainability and scalability of the application, we need to follow some best practices. This article will introduce some best practices regarding the Laravel framework and show how to implement them with code examples.
- Using Laravel’s naming convention
The Laravel framework has a set of naming conventions that can help us read and understand the code more easily. For example, model classes should use the singular form, and controller classes should use the plural form. Following these conventions will make your code more consistent and make it easier for other developers to understand and maintain your application.
The following is a code example using Laravel's naming convention:
// 模型類
class User extends Model {
// ...
}
// 控制器類
class UsersController extends Controller {
// ...
}- Using Laravel's routing function
Laravel provides a powerful routing function that can help us Define and manage your application's routes. When designing routes, you should follow a RESTful style and use a meaningful URL structure. Additionally, related routes can be organized into a controller to improve code readability and maintainability.
The following is a code example that takes advantage of Laravel's routing capabilities:
// 定義路由
Route::get('/users', 'UsersController@index');
Route::post('/users', 'UsersController@store');
Route::get('/users/{id}', 'UsersController@show');
Route::put('/users/{id}', 'UsersController@update');
Route::delete('/users/{id}', 'UsersController@destroy');
// UsersController類
class UsersController extends Controller {
public function index() {
// ...
}
public function store() {
// ...
}
public function show($id) {
// ...
}
public function update($id) {
// ...
}
public function destroy($id) {
// ...
}
}- Using Laravel's validation capabilities
Input validation is an important component of building secure web applications part. Laravel provides powerful validation features that can help us easily validate user input. Using Laravel's validation features can reduce code redundancy and improve code maintainability.
The following is a code example using Laravel's validation function:
// 定義驗(yàn)證規(guī)則
$rules = [
'name' => 'required|string|max:255',
'email' => 'required|email|unique:users',
'password' => 'required|string|min:6|confirmed',
];
// 執(zhí)行驗(yàn)證
$validator = validator(request()->all(), $rules);
if ($validator->fails()) {
// 驗(yàn)證失敗的邏輯
} else {
// 驗(yàn)證成功的邏輯
}- Database migration and population using Laravel
Database migration is a way to manage database schema changes method, while fill is used to add basic data to the database. Laravel provides database migration and population functions that can help us manage database structure and data more easily.
The following is a code example using Laravel database migration and population functionality:
// 創(chuàng)建遷移文件
php artisan make:migration create_users_table
// 編輯遷移文件
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
// 執(zhí)行遷移
php artisan migrate
// 創(chuàng)建填充文件
php artisan make:seeder UsersTableSeeder
// 編輯填充文件
public function run()
{
DB::table('users')->insert([
'name' => 'John Doe',
'email' => 'john@example.com',
'password' => bcrypt('password'),
]);
}
// 執(zhí)行填充
php artisan db:seed --class=UsersTableSeederConclusion:
By following the above Laravel best practices, we can build maintainable and Scalable applications. These practices include using Laravel's naming conventions, leveraging routing features, using validation features, and database migration and population features. I hope this article can provide valuable guidance to developers and help them better utilize the Laravel framework to build high-quality web 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
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.
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
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.
PHP development user permission management monetization PHP permission control and role management
Jul 25, 2025 pm 06:51 PM
User permission management is the core mechanism for realizing product monetization in PHP development. It separates users, roles and permissions through a role-based access control (RBAC) model to achieve flexible permission allocation and management. The specific steps include: 1. Design three tables of users, roles, and permissions and two intermediate tables of user_roles and role_permissions; 2. Implement permission checking methods in the code such as $user->can('edit_post'); 3. Use cache to improve performance; 4. Use permission control to realize product function layering and differentiated services, thereby supporting membership system and pricing strategies; 5. Avoid the permission granularity is too coarse or too fine, and use "investment"
How to use PHP combined with AI to analyze video content PHP intelligent video tag generation
Jul 25, 2025 pm 06:15 PM
The core idea of PHP combining AI for video content analysis is to let PHP serve as the backend "glue", first upload video to cloud storage, and then call AI services (such as Google CloudVideoAI, etc.) for asynchronous analysis; 2. PHP parses the JSON results, extract people, objects, scenes, voice and other information to generate intelligent tags and store them in the database; 3. The advantage is to use PHP's mature web ecosystem to quickly integrate AI capabilities, which is suitable for projects with existing PHP systems to efficiently implement; 4. Common challenges include large file processing (directly transmitted to cloud storage with pre-signed URLs), asynchronous tasks (introducing message queues), cost control (on-demand analysis, budget monitoring) and result optimization (label standardization); 5. Smart tags significantly improve visual
How to build a content payment platform through PHP How to implement PHP paid reading system
Jul 25, 2025 pm 06:30 PM
To build a PHP content payment platform, it is necessary to build a user management, content management, payment and permission control system. First, establish a user authentication system and use JWT to achieve lightweight authentication; second, design the backend management interface and database fields to manage paid content; third, integrate Alipay or WeChat payment and ensure process security; fourth, control user access rights through session or cookies. Choosing the Laravel framework can improve development efficiency, use watermarks and user management to prevent content theft, optimize performance requires coordinated improvement of code, database, cache and server configuration, and clear policies must be formulated and malicious behaviors must be prevented.
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.
