User behavior statistics and analysis using PHP to develop small programs

User behavior statistics and analysis of developing small programs using PHP

With the rapid development of the mobile Internet, small programs have become an important form of mobile applications. As a developer of mini programs, understanding and analyzing user behavior data is crucial to improving application experience and increasing user retention. This article will introduce how to use PHP to develop user behavior statistics and analysis functions of small programs, and provide corresponding code examples.

1. Preparation
Before starting, we need to ensure that the following preparations have been completed:

1. The background server environment of the mini program has been set up and has the necessary support. Database read and write permissions.
2. PHP and database connection components (such as PDO) have been installed and configured.
3. The user authentication and login functions of the mini program have been completed, and the user's unique identifier (such as openid) has been obtained.

2. User behavior statistics
User behavior statistics refers to the recording and statistics of various operations of users in mini programs, such as users opening a page, clicking a button, submitting Forms etc. Such statistics can help us understand users' usage habits and preferences, thereby optimizing the functions and interface design of the mini program.

First, we need to add corresponding event monitoring in the applet. When the user triggers a specific behavior, the corresponding statistics request will be sent to the background server. The following is a simple example:

// A page in the applet
Page({
// ...
// Listen to the page opening event
onLoad: function() {

wx.request({
  url: 'https://your-backend-server.com/statistics.php',
  data: {
    action: 'page_view',
    page: 'home',
    openid: 'user_openid'
  },
  method: 'POST'
})

},
// Listen to button click events
handleClick: function() {

wx.request({
  url: 'https://your-backend-server.com/statistics.php',
  data: {
    action: 'button_click',
    button: 'submit',
    openid: 'user_openid'
  },
  method: 'POST'
})

}
// ...
})

In the above code, we use the wx.request method provided by the applet to send a statistical request to the background server. Among them, the action parameter represents the user's behavior type, and the page or button parameter represents a specific page or button. The openid parameter is the user's unique identifier and is used to distinguish the behavior of different users.

Next, we need to write a PHP script on the backend server to handle these statistical requests. The following is a simple sample code:

//Connect to the database
$dsn = 'mysql:dbname=YOUR_DATABASE;host=YOUR_HOST';
$username = ' YOUR_USERNAME';
$password = 'YOUR_PASSWORD';
$dbh = new PDO($dsn, $username, $password);

// Process statistics request
$action = $ _POST['action'];
$openid = $_POST['openid'];

if ($action == 'page_view') {
$page = $_POST['page' ];
$stmt = $dbh->prepare("INSERT INTO statistics (openid, action, page) VALUES (?, 'page_view', ?)");
$stmt->execute([ $openid, $page]);
} elseif ($action == 'button_click') {
$button = $_POST['button'];
$stmt = $dbh->prepare( "INSERT INTO statistics (openid, action, button) VALUES (?, 'button_click', ?)");
$stmt->execute([$openid, $button]);
}

// Close the database connection
$dbh = null;
?>

In the above code, we first connected to the database and obtained the statistics request parameters sent by the user. Then according to different behavior types, corresponding statistical records are inserted into the database. Finally close the database connection.

3. User Behavior Analysis
User behavior analysis refers to the processing and analysis of user behavior data in order to extract useful information and insights, thereby helping us make reasonable decisions and improvements.

The following is a sample code for using PHP to analyze user behavior data:

// Connect to the database
$dsn = 'mysql:dbname=YOUR_DATABASE; host=YOUR_HOST';
$username = 'YOUR_USERNAME';
$password = 'YOUR_PASSWORD';
$dbh = new PDO($dsn, $username, $password);

// Count the number of page visits
$stmt = $dbh->prepare("SELECT page, COUNT(*) AS count FROM statistics WHERE action = 'page_view' GROUP BY page");
$stmt-> ;execute();
$pageViews = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Count button clicks
$stmt = $dbh->prepare(" SELECT button, COUNT(*) AS count FROM statistics WHERE action = 'button_click' GROUP BY button");
$stmt->execute();
$buttonClicks = $stmt->fetchAll(PDO: :FETCH_ASSOC);

//Output analysis results
echo 'Number of page visits:';
foreach ($pageViews as $pageView) {
echo $pageView['page'] . ': ' . $pageView['count'] . ', ';
}
echo '
';

echo 'Number of button clicks:';
foreach ($ buttonClicks as $buttonClick) {
echo $buttonClick['button'] . ': ' . $buttonClick['count'] . ', ';
}

// Close the database connection
$dbh = null;
?>

In the above code, we first connect to the database, and then use SQL statements to query statistical data. By using the GROUP BY clause, you can classify and count behavior types. Finally, we display the results as output.

Summary:
Using PHP to develop user behavior statistics and analysis functions of small programs can help us better understand users' operating habits and make corresponding improvements and optimizations based on statistical results. In practical applications, we can further improve and expand these functions according to needs, such as adding more behavior types and dimensions, using more complex data analysis algorithms, etc. I hope this article can be of some help to the statistics and analysis of user behavior when developing small programs using PHP.
