What are some strategies for optimizing the performance of PHP scripts when dealing with large log files, such as caching data or reducing file sizes?

When dealing with large log files in PHP, one strategy to optimize performance is to cache data rather than repeatedly reading from the log file. This can be achieved by storing parsed log data in memory or using a caching mechanism like Memcached or Redis. Additionally, reducing file sizes by filtering out unnecessary data or splitting large log files into smaller chunks can also help improve performance. 

// Example of caching log data in memory using an array
$logData = []; // Initialize an empty array to store log data

// Read log file line by line and store data in memory
$handle = fopen('logfile.txt', 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // Parse log data and store in array
        $logData[] = parseLogLine($line);
    }
    fclose($handle);
}

// Function to parse log line
function parseLogLine($line) {
    // Parse log line and return structured data
    return $parsedData;
}
