Develop WeChat applet with PHP: How to implement data analysis?

With the popularity of WeChat mini programs and the expansion of their application scope, the demand for data analysis is also increasing. In the process of developing WeChat mini programs, data analysis is a very important part. Through data analysis, we can understand users' behavioral habits and user group characteristics, so as to carry out targeted optimization and improvement to enhance the user experience of mini programs.

This article will introduce how to use PHP to develop the data analysis function of WeChat applet and provide specific code examples.

1. Data burying points

Data burying points are the basis of data analysis. By burying points in the code of WeChat applet, various behavioral data of users can be collected. Common data burying points include:

1. Page access: When a user accesses a page, the user's access time and page ID are recorded.
2. Button click: When the user clicks a button, record the button ID and click time.
3. Form submission: When the user submits a form, record the form ID and submission time.

In the WeChat applet, you can send a data burying request to the server through the wx.request method. The server side can receive and handle these requests using PHP.

The following is an example of sending data buried points to the server:

wx.request({
  url: 'http://example.com/track.php',
  data: {
    page: 'homepage',
    action: 'visit',
    time: Date.now()
  },
  success: function (res) {
    console.log('数据埋点成功');
  },
  fail: function (err) {
    console.error('数据埋点失败', err);
  }
})

2. Data storage

PHP can be used as a server-side language to receive and store data buried points ask. Databases such as MySQL and Redis can be used to store data. The following takes MySQL as an example to illustrate how to use PHP to implement data storage.

1. Create database and data table:

CREATE DATABASE `wechat_app` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE TABLE `track` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `page` VARCHAR(50) NOT NULL,
  `action` VARCHAR(50) NOT NULL,
  `time` INT(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

2. Write PHP code to receive and process data burying requests, and store data in the database:

<?php

// 连接数据库
$servername = "localhost";
$username = "root";
$password = "123456";
$dbname = "wechat_app";

$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
  die("连接失败: " . mysqli_connect_error());
}

// 接收数据埋点请求
$page = $_POST['page'];
$action = $_POST['action'];
$time = $_POST['time'];

// 将数据存储到数据库中
$sql = "INSERT INTO track (page, action, time) VALUES ('$page', '$action', '$time')";

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

By storing user behavior data in the database, we can use PHP to write data analysis code to obtain and analyze these data.

The following is a simple data analysis example that counts the number of times users access the mini program every day:

<?php

// 连接数据库
$servername = "localhost";
$username = "root";
$password = "123456";
$dbname = "wechat_app";

$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
  die("连接失败: " . mysqli_connect_error());
}

// 获取每天的访问次数
$sql = "SELECT DATE_FORMAT(FROM_UNIXTIME(`time`), '%Y-%m-%d') AS `day`, COUNT(*) AS `count` FROM track WHERE `action` = 'visit' GROUP BY `day`";

$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0) {
  while ($row = mysqli_fetch_assoc($result)) {
    echo "日期: " . $row['day'] . "，访问次数: " . $row['count'] . "<br>";
  }
}

mysqli_close($conn);

?>

In the above example code, through the SQL statement SELECT DATE_FORMAT(FROM_UNIXTIME( time), '%Y-%m-%d') AS day, COUNT(*) AS count FROM track WHERE action = ' visit' GROUP BY day`", query the number of visits per day and group them by date.

Through the above steps, we can implement the data analysis function of using PHP to develop WeChat applet. According to actual needs, you can Write corresponding code to implement more complex data analysis.

Summary:

This article introduces how to use PHP to develop the data analysis function of WeChat applet and provides specific code examples. By Through data burying, data storage and data analysis, we can understand users' behavioral habits and characteristics, thereby providing a reference for the optimization and improvement of WeChat mini programs. I hope this article will be helpful for the development of data analysis for WeChat mini programs.
