PHP development of WeChat applet: EasyWeChat implements user points management function

Introduction:
WeChat applet is an emerging application development platform, and more and more developers are beginning to pay attention to and use it. In the development of WeChat mini programs, user points management is one of the common requirements. This article will introduce how to use PHP to develop WeChat applet and implement user points management function through EasyWeChat.

What is EasyWeChat?
EasyWeChat is an open source WeChat SDK based on PHP, which provides rich functions and simple API interfaces to facilitate developers to quickly integrate WeChat related functions into their own applications. It supports the development of WeChat official accounts, WeChat payment, WeChat mini programs and other platforms.

Step 1: Install EasyWeChat
First, we need to install EasyWeChat into our development environment. Run the following command in the terminal:

composer require overtrue/wechat

This will install the dependencies required by EasyWeChat.

Step 2: Create a mini program and obtain the AppID and AppSecret
Create a mini program on the WeChat public platform and obtain the AppID and AppSecret of the mini program, which will be used in subsequent development.

Step 3: Configure EasyWeChat
Create a config.php file in the project to store the configuration information of EasyWeChat. The configuration is as follows:

<?php
return [
    'mini_program' => [
        'app_id' => 'your_app_id',
        'secret' => 'your_app_secret',
    ],
];

Replace your_app_id and your_app_secret with the AppID and AppSecret obtained previously.

Step 4: Create a points operation class
Create a Points class in the project, which is used to handle the addition and query of user points. The code is as follows:

<?php
class Points
{
    protected $app;
    
    public function __construct()
    {
        $options = require 'config.php';
        $this->app = new EasyWeChatFoundationApplication($options);
    }
    
    public function addPoints($openid, $points)
    {
        $member = new EasyWeChatMiniProgramMemberMember($this->app);
        $member->update($openid, ['points' => $points]);
    }
    
    public function getPoints($openid)
    {
        $member = new EasyWeChatMiniProgramMemberMember($this->app);
        $info = $member->get($openid);
        return $info['points'];
    }
}

Step 5: Use the points operation class
Introduce the Points class and create an instance where the points function needs to be used. For example, the sample code for adding points and querying points is as follows:

<?php
require 'Points.php';

$points = new Points();

// 增加积分
$openid = 'user_openid';
$points->addPoints($openid, 100);

// 查询积分
$userPoints = $points->getPoints($openid);
echo "用户积分为：" . $userPoints;

Summary:
This article introduces how to use PHP to develop WeChat applet and implement user points management function through EasyWeChat. This involves the installation and configuration of EasyWeChat, as well as the use of custom classes to handle the addition and query of user points. I hope this article will be helpful to developers who are developing WeChat mini programs.
