What are some best practices for efficiently processing and manipulating log data in PHP scripts?

When processing and manipulating log data in PHP scripts, it is important to efficiently handle large volumes of data to avoid performance issues. One best practice is to use streaming techniques to read and write log data in chunks rather than loading the entire file into memory at once. Additionally, using regex patterns or built-in string functions can help efficiently extract and manipulate specific log entries. 

// Example of efficiently processing and manipulating log data in PHP

// Open log file for reading
$handle = fopen('logs.txt', 'r');

// Read and process log entries line by line
while (($line = fgets($handle)) !== false) {
    // Manipulate log data as needed
    // Example: extract timestamp and message
    $logParts = explode(' - ', $line);
    $timestamp = trim($logParts[0]);
    $message = trim($logParts[1]);
    
    // Output processed log entry
    echo "Timestamp: $timestamp, Message: $message\n";
}

// Close log file
fclose($handle);
