What is the purpose of analyzing access logs in PHP and how can it be done efficiently?

Analyzing access logs in PHP can help track user activity, monitor website performance, and identify potential security threats. To efficiently analyze access logs, you can parse the log files and extract relevant information such as IP addresses, timestamps, requested URLs, and response codes. 

<?php
$logFile = '/path/to/access.log';

if (file_exists($logFile)) {
    $handle = fopen($logFile, 'r');
    
    while (($line = fgets($handle)) !== false) {
        // Parse each log entry and extract relevant information
        // Example: $logData = explode(' ', $line);
        
        // Perform analysis or store data as needed
    }
    
    fclose($handle);
} else {
    echo 'Access log file not found.';
}
?>
