How to use PHP to develop a member management system for WeChat public accounts

With the rapid development of the mobile Internet, WeChat has become an indispensable part of people's lives. As an important social platform, WeChat official account provides an important channel for individuals and enterprises to communicate with users. In WeChat public accounts, the membership management system is widely used, which can help companies better manage user information and provide personalized services. This article will introduce how to use PHP to develop a member management system for WeChat public accounts, including functions such as obtaining user information and managing members, and attaches specific code examples.

1. Get user information

In the WeChat public account, we can obtain the user's basic information by calling the interface of the WeChat open platform. First, we need to register and create an application on the WeChat open platform and obtain the appid and appsecret. We can then use this information to implement the function of obtaining user information through PHP code. The specific code is as follows:

<?php
$appid = 'your_appid';
$appsecret = 'your_appsecret';

$code = $_GET['code']; // 用户授权时获取到的code
// 换取access_token
$url = 'https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code';
$result = file_get_contents($url);
$json = json_decode($result, true);
$access_token = $json['access_token'];
$openid = $json['openid'];

// 获取用户信息
$user_info_url = 'https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN';
$user_info_result = file_get_contents($user_info_url);
$user_info = json_decode($user_info_result, true);

// 打印用户信息
echo '昵称：'.$user_info['nickname'].'<br>';
echo '性别：'.$user_info['sex'].'<br>';
echo '城市：'.$user_info['city'].'<br>';
echo '头像：<img  src="'.$user_info['headimgurl'].'" alt="How to use PHP to develop a member management system for WeChat public accounts" >';
?>

Through the above code, you can get the user's nickname, gender, city and avatar URL. You can store this information in the database as needed for subsequent membership management and personalized services.

2. Manage members

Member management is one of the important functions of WeChat official accounts. We can implement functions such as adding members, querying members, and updating members through the WeChat interface. The following is a simple example that demonstrates how to implement the function of adding members through PHP code.

<?php
$appid = 'your_appid';
$appsecret = 'your_appsecret';

// 获取access_token
$access_token_url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$appid.'&secret='.$appsecret;
$access_token_result = file_get_contents($access_token_url);
$access_token_json = json_decode($access_token_result, true);
$access_token = $access_token_json['access_token'];

// 添加会员
$add_member_url = 'https://api.weixin.qq.com/cgi-bin/membercard/activate?access_token='.$access_token;
$data = array(
  'init_bonus' => 100,
  'init_balance' => 1000,
  'membership_number' => '123456789',
  'code' => '123456789',
  'card_id' => 'your_card_id',
  'background_pic_url' => 'your_background_pic_url',
  'bonus_url' => 'your_bonus_url',
);
$data = json_encode($data);
$add_member_result = file_get_contents($add_member_url, false, stream_context_create(array(
  'http' => array(
    'method' => 'POST',
    'header' => 'Content-type: application/json',
    'content' => $data,
  ),
)));
$add_member_json = json_decode($add_member_result, true);
if ($add_member_json['errcode'] == 0) {
  echo '会员添加成功';
} else {
  echo '会员添加失败：'.$add_member_json['errmsg'];
}
?>

Through the above code, you can realize the function of adding members. You need to replace your_card_id, your_background_pic_url and your_bonus_url with your specific information. . In this way, when a user applies for membership in the official account, you can use this code to add the user to the membership list.
