What best practices should be followed when copying PHP files and modifying user/group settings in a script?

When copying PHP files and modifying user/group settings in a script, it is important to ensure that the permissions are set correctly to maintain security. To do this, you can use the `chmod` function in PHP to set the appropriate permissions for the copied files. Additionally, it is recommended to follow the principle of least privilege and only grant necessary permissions to users and groups. 

// Copy the file
$source = 'original_file.php';
$destination = 'copied_file.php';
copy($source, $destination);

// Set permissions for the copied file
chmod($destination, 0644); // Set read and write permissions for owner, read permissions for group and others
