How can PHP developers effectively analyze log files to track website visitor activity in real-time?

To effectively analyze log files to track website visitor activity in real-time, PHP developers can use tools like tail or grep to monitor log files as they are updated. By continuously monitoring the log files, developers can extract relevant information such as IP addresses, timestamps, and requested URLs to track visitor activity in real-time. 

<?php
$logFile = '/var/log/apache2/access.log';

// Continuously monitor the log file for updates
$fp = fopen($logFile, 'r');
while (true) {
    while ($line = fgets($fp)) {
        // Extract relevant information from the log line
        $parts = explode(' ', $line);
        $ipAddress = $parts[0];
        $timestamp = $parts[3] . ' ' . $parts[4];
        $url = $parts[6];

        // Process and track visitor activity in real-time
        echo "IP Address: $ipAddress | Timestamp: $timestamp | URL: $url\n";
    }
    usleep(1000000); // Wait for 1 second before checking for updates
}
fclose($fp);
?>
