Data analysis and user portraits using PHP to develop small programs

With the rapid development of the mobile Internet, small programs have become a very popular application form. In the process of operating mini programs, data analysis and user portraits are very important tasks. This article will introduce how to use PHP language to develop data analysis and user portrait systems for small programs.

1. Design of data analysis system

1. Data collection

Data collection is the first step of data analysis. We need to collect users of the mini program Behavior, visits, page dwell time and other related data. These data can be collected through the API interface provided by the mini program backend.

Sample code:

// 获取小程序访问记录
function getMiniprogramVisitData($access_token, $start_date, $end_date) {
    $url = "https://api.weixin.qq.com/datacube/getweanalysisappidvisitpage?access_token=" . $access_token;
    $data = array(
        "begin_date" => $start_date,
        "end_date" => $end_date
    );
    $json_data = json_encode($data);
  
    // 发起网络请求，获取数据
    $result = http_post($url, $json_data);
    $result = json_decode($result, true);
    return $result;
}

// 发送POST请求
function http_post($url, $data) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}

2. Data storage

We can use databases such as MySQL to store the collected data for subsequent analysis and use. We need to design an appropriate data table structure to store the collected data.

Sample code:

// 存储小程序访问记录
function saveMiniprogramVisitData($data) {
    $conn = mysqli_connect("localhost", "root", "password", "database");
    if (!$conn) {
        die("连接数据库失败：" . mysqli_connect_error());
    }
  
    $sql = "INSERT INTO visit_data (date, visit_uv, visit_pv) VALUES ('" . $data['date'] . "', " . $data['visit_uv'] . ", " . $data['visit_pv'] . ")";
    if (mysqli_query($conn, $sql)) {
        echo "数据存储成功";
    } else {
        echo "数据存储失败：" . mysqli_error($conn);
    }
  
    mysqli_close($conn);
}

3. Data analysis

In the data analysis process, we can use various statistical methods and algorithms, such as average, Bar charts, line charts, etc., to analyze and display the collected data. PHP provides a wealth of chart libraries and data processing functions, and we can use these tools to perform data analysis.

Sample code:

// 统计小程序访问次数
function countMiniprogramVisitTimes($start_date, $end_date) {
    $conn = mysqli_connect("localhost", "root", "password", "database");
    if (!$conn) {
        die("连接数据库失败：" . mysqli_connect_error());
    }
  
    $sql = "SELECT COUNT(*) AS visit_times FROM visit_data WHERE date >= '" . $start_date . "' AND date <= '" . $end_date . "'";
    $result = mysqli_query($conn, $sql);
    $row = mysqli_fetch_assoc($result);
  
    mysqli_close($conn);
    return $row['visit_times'];
}

2. Design of user portrait system

1. User data collection

User data collection is to draw users On the basis of profiling, we need to collect users’ basic information and behavioral characteristics. In the mini program, we can obtain the user's WeChat ID, geographical location, purchase record and other information through user authorization.

Sample code:

// 获取用户微信号
function getUserWechatId($access_token, $code) {
    $url = "https://api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=APPSECRET&js_code=" . $code . "&grant_type=authorization_code";
    $result = http_get($url);
    $result = json_decode($result, true);
    $wechat_id = $result['openid'];
    return $wechat_id;
}

// 发送GET请求
function http_get($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}

2. User profile generation

User profile generation is based on the analysis of user behavior and characteristics. We need to use data mining and machines Learning and other methods are used to generate user portraits. PHP provides many data analysis and machine learning libraries and functions, such as scikit-learn and tensorflow, etc. We can use these tools to generate user portraits.

Sample code:

// 生成用户画像
function generateUserPortrait($user_id) {
    $conn = mysqli_connect("localhost", "root", "password", "database");
    if (!$conn) {
        die("连接数据库失败：" . mysqli_connect_error());
    }
  
    $sql = "SELECT * FROM user_data WHERE user_id = " . $user_id;
    $result = mysqli_query($conn, $sql);
    $row = mysqli_fetch_assoc($result);
  
    // 对用户数据进行分析和处理
    // ...
  
    mysqli_close($conn);
    return $user_portrait;
}

3. Summary

This article introduces how to use PHP to develop data analysis and user profiling systems for small programs. Through data analysis, we can monitor the operation of mini programs in real time and adjust optimization strategies in a timely manner; through user portraits, we can better understand user needs and behavioral characteristics, thereby providing better user experience and services. I hope the above content will be helpful for data analysis and user portrait development of mini programs.
