Second-hand recycling website developed in PHP to implement user behavior analysis function

The second-hand recycling website developed by PHP realizes the user behavior analysis function

With the development of the Internet, second-hand recycling websites have become an important way for people to deal with idle items. In order to better understand users' behavioral habits and needs in order to provide better services, we can obtain valuable information about users by developing a set of user behavior analysis functions. This article will introduce how to use PHP to develop the user behavior analysis function of a second-hand recycling website, and illustrate it through code examples.

1. Data statistics and collection
Before implementing the user behavior analysis function, data statistics and collection must first be carried out. We can collect user behavioral data in the following ways:

1. Access logs: By recording users’ access logs, including access time, IP address, browser type and other information, we can understand the user’s Activity and access habits.
2. User operation log: records the user's operation behavior, such as searching for keywords, browsing products, adding to the shopping cart, etc., and can analyze the user's preferences and interests.
3. Transaction data: Record the user's purchasing behavior, such as purchasing goods, payment amount, etc., which can evaluate the user's spending power and purchasing tendency.

The above data can be collected and recorded through server-side PHP code. The following is a simple sample code:

// 记录用户访问日志
function logVisit($ip, $uri, $referer, $userAgent) {
    $logFile = 'visit.log';
    $logData = $ip . '|' . date('Y-m-d H:i:s') . '|' . $uri . '|' . $referer . '|' . $userAgent . "
";
    file_put_contents($logFile, $logData, FILE_APPEND);
}

// 记录用户操作日志
function logAction($userId, $action, $data) {
    $logFile = 'action.log';
    $logData = $userId . '|' . date('Y-m-d H:i:s') . '|' . $action . '|' . json_encode($data) . "
";
    file_put_contents($logFile, $logData, FILE_APPEND);
}

// 记录用户交易数据
function logTransaction($userId, $orderId, $amount) {
    $logFile = 'transaction.log';
    $logData = $userId . '|' . date('Y-m-d H:i:s') . '|' . $orderId . '|' . $amount . "
";
    file_put_contents($logFile, $logData, FILE_APPEND);
}

// 示例代码调用
$logIp = $_SERVER['REMOTE_ADDR'];
$logUri = $_SERVER['REQUEST_URI'];
$logReferer = $_SERVER['HTTP_REFERER'];
$logUserAgent = $_SERVER['HTTP_USER_AGENT'];
logVisit($logIp, $logUri, $logReferer, $logUserAgent);

2. Data storage and analysis
Next, the collected user behavior data needs to be stored in the database and analyzed. We can use MySQL as the database and use PHP code to store and analyze data. The following is a simple sample code:

// 连接数据库
$host = 'localhost';
$dbname = 'analytic';
$username = 'root';
$password = '123456';
try {
    $db = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
} catch (PDOException $e) {
    die('数据库连接失败：' . $e->getMessage());
}

// 记录用户访问日志
function logVisit($ip, $uri, $referer, $userAgent) {
    global $db;
    $sql = "INSERT INTO visit_logs (ip, uri, referer, user_agent) VALUES (:ip, :uri, :referer, :user_agent)";
    $stmt = $db->prepare($sql);
    $stmt->bindParam(':ip', $ip);
    $stmt->bindParam(':uri', $uri);
    $stmt->bindParam(':referer', $referer);
    $stmt->bindParam(':user_agent', $userAgent);
    $stmt->execute();
}

// 记录用户操作日志
function logAction($userId, $action, $data) {
    global $db;
    $sql = "INSERT INTO action_logs (user_id, action, data) VALUES (:user_id, :action, :data)";
    $stmt = $db->prepare($sql);
    $stmt->bindParam(':user_id', $userId);
    $stmt->bindParam(':action', $action);
    $stmt->bindParam(':data', $data);
    $stmt->execute();
}

// 记录用户交易数据
function logTransaction($userId, $orderId, $amount) {
    global $db;
    $sql = "INSERT INTO transaction_logs (user_id, order_id, amount) VALUES (:user_id, :order_id, :amount)";
    $stmt = $db->prepare($sql);
    $stmt->bindParam(':user_id', $userId);
    $stmt->bindParam(':order_id', $orderId);
    $stmt->bindParam(':amount', $amount);
    $stmt->execute();
}

// 示例代码调用
$logIp = $_SERVER['REMOTE_ADDR'];
$logUri = $_SERVER['REQUEST_URI'];
$logReferer = $_SERVER['HTTP_REFERER'];
$logUserAgent = $_SERVER['HTTP_USER_AGENT'];
logVisit($logIp, $logUri, $logReferer, $logUserAgent);

3. Data analysis and display
By storing user behavior data, we can perform data analysis and display to understand the user's behavioral habits and needs. The following is a simple sample code to display user access statistics:

// 统计访问次数
function countVisits() {
    global $db;
    $sql = "SELECT COUNT(*) AS visits FROM visit_logs";
    $stmt = $db->prepare($sql);
    $stmt->execute();
    $result = $stmt->fetch(PDO::FETCH_ASSOC);
    return $result['visits'];
}

// 示例代码调用
$visits = countVisits();
echo '总访问次数：' . $visits;

The above is the method and sample code for using PHP to develop the user behavior analysis function of a second-hand recycling website. By collecting and analyzing user behavior data, we can better understand user needs and thereby provide better services and user experience. Hope this helps!
