How can recursion be utilized to efficiently copy directories and files to another server in PHP?

To efficiently copy directories and files to another server in PHP, recursion can be utilized to traverse through the directory structure and copy each file and subdirectory. By recursively copying files and directories, we can ensure that the entire structure is replicated accurately on the destination server. 

function copyDirectory($src, $dest) {
    $dir = opendir($src);
    @mkdir($dest);

    while(false !== ($file = readdir($dir))) {
        if (($file != '.') && ($file != '..')) {
            if (is_dir($src . '/' . $file)) {
                copyDirectory($src . '/' . $file, $dest . '/' . $file);
            } else {
                copy($src . '/' . $file, $dest . '/' . $file);
            }
        }
    }

    closedir($dir);
}

copyDirectory('/path/to/source/directory', '/path/to/destination/directory');
