Quick Start with ThinkPHP6 Programming

ThinkPHP6 is an MVC architecture framework based on the PHP language. It is an excellent PHP framework chosen by many developers. It has very high performance, ease of use, and rich scalability, which can well meet the needs of various applications. If you want to learn PHP development or are looking for an excellent PHP framework, ThinkPHP6 is not to be missed. This article will introduce readers to the basic knowledge and quick programming methods of ThinkPHP6 from an entry-level perspective.

1. Environment preparation

Before starting to use ThinkPHP6 for development, you need to install and prepare some pre-environment:

1. PHP installation

First you need to install the PHP environment. You can download the PHP package from the PHP official website: https://windows.php.net/download/. When downloading, choose the version that matches your system and the web server you are targeting, such as Apache or Nginx. You can use comprehensive software packages such as XAMPP or WAMP, or you can install it manually.

2. Composer installation

Composer is a dependency management tool for PHP that can automatically download and manage framework and library dependencies. You can download the Composer package from the Composer official website: https://getcomposer.org/download/, and then install it according to the instructions.

3. ThinkPHP6 installation

Use Composer for automated installation. Just open it in the terminal and execute the following command:

composer create-project topthink /think tp6

After the installation is completed, we can access it on the local server and view the effect.

2. Basic knowledge

1. Directory structure

The directory structure of ThinkPHP6 is similar to other MVC frameworks. You can use the following directories when making initial contact. Understand:

• app directory

This is the main directory of the application, mainly used to store controllers, models, view files, etc.

• config directory

This is the configuration directory of the application, which stores all the configuration information of the application.

• public directory

This directory stores the public resource files of the application, such as CSS, JavaScript, images, etc.

• route directory

This directory stores the routing configuration file of the application. By default, routing is automatic, but we can also configure manual routing.

2. MVC design pattern

ThinkPHP6 uses the MVC (Model-View-Controller) design pattern, where M refers to the model related to database data operations, and V refers to the view related to user interaction, and C refers to the controller that handles requests and responses.

3. URL and routing

In ThinkPHP6, all requests are accessed through URLs. URL is composed of protocol, domain name, path, file name, parameters, etc., while routing refers to the process of matching URL with controllers and methods. Routing can be set manually, or you can use the automatic routing mode to directly access the corresponding controller and method through the parameters of the URL.

3. Programming Example

The following is a simple programming example, which contains a controller and some simple view files.

1. Controller

In the controller we can define many different processors, such as processing form submission, querying and inserting into the database. The following is an example of a controller named Index:

26c787bcc2ab1a0bd06a2a8ebdc77548

Here we define two processors, the index processor returns the view, and the hello processor returns the corresponding output value based on the input parameters.

2. View

In the view file we can define many different HTML elements, such as forms, text, titles, etc. The following is an example of a simple view file:

<title>Welcome to ThinkPHP6</title>

<?php echo 'Hello, ThinkPHP6!'; ?>

73a6ac4ed44ffec12cee46588e518a5e

Here we use an HTML format document, And output the output value as text.

3. Routing

Through routing we can map the URL to the corresponding controller and method. The following is an example of routing settings:

b47ec4569797643c41c24f5892e403f0

Here we set two routes, of which the first One route maps the root path of the application to the index method in the Index controller, while the second route maps the /hello path to the hello method in the Index controller, and passes :name as a parameter to the hello method. .

4. Summary

This article introduces some basic ThinkPHP6 programming knowledge and skills, including environment preparation, directory structure, MVC design pattern, URL and routing, and programming examples. Through this knowledge and skills, we can master and apply the ThinkPHP6 framework for development more quickly and effectively. If you want to learn more about the use and application of ThinkPHP6, you can refer to the official ThinkPHP6 documentation, or find relevant information and tutorials online. I wish you better results in ThinkPHP6 programming!
