How can PHP developers improve the performance of reading and processing log files by implementing a more efficient data handling strategy?

Issue: PHP developers can improve the performance of reading and processing log files by implementing a more efficient data handling strategy, such as using buffered reading and processing chunks of data at a time instead of reading the entire file at once.

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

// Buffer size for reading chunks of data
$buffer_size = 4096;

// Read and process data in chunks
while (!feof($file)) {
    $data = fread($file, $buffer_size);
    
    // Process data here
    
    // Clear the buffer
    ob_flush();
    flush();
}

// Close the file
fclose($file);
