What are the best practices for optimizing file handling operations in PHP when working with flatfile databases?

When working with flatfile databases in PHP, it is crucial to optimize file handling operations to ensure efficient read and write processes. One of the best practices is to minimize the number of file operations by caching data in memory whenever possible. Additionally, using file locking mechanisms can prevent data corruption when multiple processes are accessing the database concurrently. 

// Example of optimizing file handling operations in PHP when working with flatfile databases

// Open the file for reading and writing
$filename = 'database.txt';
$handle = fopen($filename, 'r+');

// Lock the file for exclusive access
if (flock($handle, LOCK_EX)) {
    // Read and modify data as needed
    $data = fread($handle, filesize($filename));
    
    // Write updated data back to the file
    fseek($handle, 0);
    fwrite($handle, $updatedData);
    
    // Release the lock and close the file
    flock($handle, LOCK_UN);
    fclose($handle);
} else {
    echo 'Could not lock the file.';
}
