PHP를 사용하여 사용자 액세스 로그 및 행동 분석 기능을 구현하는 방법

// 记录用户访问日志
function logVisit($userId, $pageName) {
    $logFile = 'visit.log';
    $logContent = date('Y-m-d H:i:s') . " - User $userId visited $pageName" . PHP_EOL;
    file_put_contents($logFile, $logContent, FILE_APPEND);
}

// 调用示例
logVisit(123, 'homepage');
logVisit(456, 'product_detail');

// 统计用户访问次数和热门页面
function analyzeUserBehavior() {
    $logFile = 'visit.log';
    $logContent = file_get_contents($logFile);
    $logArray = explode(PHP_EOL, $logContent);
    $userCount = array();
    $pageCount = array();

    foreach ($logArray as $logLine) {
        $logItems = explode(" - ", $logLine);
        if (count($logItems) != 2) {
            continue;
        }

        $userId = substr($logItems[1], 5, 3);
        $pageName = substr($logItems[2], 15);
        
        // 统计用户访问次数
        if (array_key_exists($userId, $userCount)) {
            $userCount[$userId]++;
        } else {
            $userCount[$userId] = 1;
        }
        
        // 统计页面访问次数
        if (array_key_exists($pageName, $pageCount)) {
            $pageCount[$pageName]++;
        } else {
            $pageCount[$pageName] = 1;
        }
    }

    // 输出结果
    echo "User visit count:" . PHP_EOL;
    foreach ($userCount as $userId => $count) {
        echo "User $userId visited $count times" . PHP_EOL;
    }

    echo "Page visit count:" . PHP_EOL;
    foreach ($pageCount as $pageName => $count) {
        echo "Page $pageName visited $count times" . PHP_EOL;
    }
}

// 调用示例
analyzeUserBehavior();
