How to use ThinkPHP6 efficiently

With the rapid development and popularity of the Internet, Web development has increasingly become a practical skill. In this process, choosing a suitable development framework can make the development process smoother and more efficient. Among them, ThinkPHP6 is a very popular PHP framework that can help developers quickly build web applications. So how to use ThinkPHP6 efficiently? This article will answer it for you.

1. Familiar with the basics of ThinkPHP6

Before using ThinkPHP6, we first need to be familiar with its basics. This includes mastering ThinkPHP6's MVC architecture, routing system, database operations, template engine, validators, helper functions, etc.

MVC architecture refers to dividing the application into three parts: Model, View and Controller. The routing system is the controller and methods defined in the URL. Database operation refers to using the built-in database operation function of ThinkPHP6 to connect to the database and perform operations such as adding, deleting, modifying, and querying data. The template engine is a way to achieve front-end and back-end separation, allowing us to easily edit and maintain front-end pages. Validators can help us verify whether the data submitted by the form meets the specifications. Helper functions include commonly used function libraries, such as cache(), encrypt(), dump(), etc.

2. Learn the naming convention of ThinkPHP6

In the process of using ThinkPHP6, it is very important to comply with the naming convention. This includes naming conventions for controllers and models, using uppercase letters to define constants, using lowercase letters to define variable and method names, etc.

In ThinkPHP6, controller names generally start with a capital letter and should end with "Controller" when naming. For example: IndexController.php, UserControlller.php, etc. The model ends with "Model", for example: UserModel.php, ArticleModel.php, etc.

3. Use Composer to manage third-party libraries

In web development, we often need to use some third-party libraries to increase our functionality. Using Composer can help us manage these third-party libraries more conveniently. To use Composer, you need to create a file named composer.json in the project root directory and define the third-party libraries that need to be introduced. For example:

{
    "require": 
        {
            "monolog/monolog": "^1.0"
        }
}

Using the composer install command will automatically install this third-party library and download it to the /vendor directory. To import this library into the project, just add:

require 'vendor/autoload.php';

to our PHP file and then you can use the functions and classes in this library.

4. Using Middleware middleware

Middleware middleware is a mechanism for efficiently managing HTTP requests and responses in applications. Using Middleware middleware can help us deal with issues such as cross-domain and HTTP authentication. In ThinkPHP6, we can customize Middleware middleware and use it in applications.

For example, we can write an AuthMiddleware middleware to implement the authentication function. The writing process is as follows:

(1) Define an AuthMiddleware middleware class

namespace appmiddleware;

class AuthMiddleware
{
    public function handle($request, Closure $next)
    {
        if (!isset($_SESSION['user_id'])) {
            // 如果不存在session信息，则跳转到登录页面
            return redirect('/login');
        }

        return $next($request);
    }
}

(2) Use AuthMiddleware middleware in routing

Route::get('/user', 'UserController@index')->middleware('AuthMiddleware');

In this way, when the user accesses /user When routing, the AuthMiddleware middleware will be executed. If the user does not have session information, it will automatically jump to the login page.

In the Conclusion, we can find that familiarity with the basic knowledge of ThinkPHP6, learning the naming convention of ThinkPHP6, using Composer to manage third-party libraries, using Middleware middleware and other techniques can help us use ThinkPHP6 more quickly and efficiently. This will make our development process more smooth and comfortable, improve our development efficiency, and make our web applications more excellent and easier to maintain.
