As an important Internet platform, WeChat official account has brought many opportunities and challenges to enterprises and individuals. When developing WeChat public accounts, the personal center is one of the most important functions for users. The following will introduce how to use PHP to develop the personal center of WeChat official account, and give specific code examples.

1. Create database and related tables
   First you need to create a user table in the database to store user-related information. The following is an example user table structure:

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    openid VARCHAR(50) NOT NULL,
    nickname VARCHAR(50) NOT NULL,
    avatar VARCHAR(255) NOT NULL,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

2. Get the user’s basic WeChat information
   In the personal center, we need to display the user’s basic WeChat information, including avatar, nickname, etc. . First, you need to obtain the user's basic information through WeChat authorization. The following is an example code for obtaining the user's basic information on WeChat:

<?php

// 获取用户授权
$userInfo = $wechat->getUserInfo($_GET['code']);
$openid = $userInfo['openid'];
$nickname = $userInfo['nickname'];
$avatar = $userInfo['headimgurl'];

// 保存用户信息到数据库
$db->query("INSERT INTO users (openid, nickname, avatar) VALUES ('$openid', '$nickname', '$avatar')");

3. Display personal center page
   In the personal center page, we need to display the user's basic information and provide some User-related functions. The following is the code of an example personal center page:

<?php

// 获取用户信息
$user = $db->query("SELECT * FROM users WHERE openid = '$openid'")->fetch(PDO::FETCH_ASSOC);

// 展示用户头像和昵称
echo "<img src='{$user['avatar']}' alt='{$user['nickname']}' />";
echo "<h2 id="user-nickname">{$user['nickname']}</h2>";

// 展示其他个人中心功能
echo "<a href='#'>我的订单</a>";
echo "<a href='#'>我的收藏</a>";
echo "<a href='#'>个人设置</a>";

Through the above code example, we can implement basic personal center functions, display the user's basic information, and provide some user-related functions. Of course, according to specific needs, we can further expand the functions of the personal center.
