How to implement data statistics of WeChat applet in PHP

With the popularity of WeChat mini programs, more and more companies and developers are beginning to use WeChat mini programs to provide services. Therefore, it is very important for developers to understand the statistics of WeChat mini programs. This article will introduce how to use PHP to develop data statistics for WeChat mini programs.

1. Understand the data statistics of WeChat mini programs

The data statistics of WeChat mini programs are divided into two types: operational data and behavioral data. Operational data refers to the overall operating data of the mini program, such as user visits, user duration, conversion rate, etc. Behavioral data refers to the user's specific behavior in the mini program, such as which buttons the user clicked, which pages he browsed, etc. The data statistics of WeChat mini programs are mainly queried and analyzed by accessing the mini program background.

2. Use PHP to implement data statistics on WeChat mini programs

1. Obtain developer ID and application secret key

Data on WeChat mini programs Before statistics, you need to obtain the developer ID and application key. Only with this information can data statistics operations be performed in the background of the WeChat applet. The method of obtaining is as follows:

(1) Log in to the WeChat public platform developer center.

(2) Enter the mini program management page and select the corresponding mini program.

(3) In the mini program management page, select "Develop" - "Development Settings" - "Developer ID and Application Key".

(4) Save the obtained developer ID and application key.

2. Configure PHP SDK

Since the data statistics of the WeChat applet are mainly queried and analyzed by accessing the background of the applet, it is necessary to use the SDK provided by the WeChat applet. Here we use PHP SDK to implement data statistics. The specific configuration method is as follows:

(1) First, download the PHP SDK on GitHub and extract the downloaded compressed package to the root directory of the project.

(2) Create a config.php file in the project root directory and fill in your developer ID and application key. The specific format is as follows:

$config = array(
    'appid' => '开发者ID',
    'secret' => '应用秘钥'
);

(3) In PHP SDK is introduced into the project, and the specific code is as follows:

require_once '路径/wx-sdk/lib/WxPay.Api.php';

3. Data statistics code implementation

After configuring the SDK, you can start data statistics. Here we take obtaining visits to a mini program as an example. The specific implementation code is as follows:

// 获取access token
$accessToken = WxPayApi::getAccessToken($config['appid'], $config['secret']);

// 获取小程序访问数据
$url = "https://api.weixin.qq.com/datacube/getweanalysisappiddailysummarytrend?access_token={$accessToken}";
$date = date('Y-m-d', time() - 24 * 3600);
$data = array(
    'begin_date' => $date,
    'end_date' => $date
);
$result = WxPayApi::httpPost($url, json_encode($data));

// 解析返回结果
$data = json_decode($result, true);
if (isset($data['list'])) {
    $visitTotal = $data['list'][0]['visit_total'];
} else {
    echo '获取小程序访问数据失败';
}

First obtain the access token through the SDK, and then call the mini program's data query API to obtain the mini program's access data. Finally, parse and return the results to obtain the number of visits to the mini program.

3. Summary

By using PHP to develop data statistics of WeChat mini programs, developers can understand the overall operation of the mini program and the specific behavior of users, and provide information for the subsequent development and optimization of the mini program. for reference. At the same time, it also improved its own development skills and experience.
