Are there any specific PHP functions or libraries that are recommended for handling file transfers between webspaces?

When transferring files between webspaces, it is recommended to use PHP's built-in functions such as `copy()` or `move_uploaded_file()` for handling file transfers. Additionally, you can use libraries like Flysystem or Guzzle for more advanced file transfer operations.

// Using copy() function for transferring files
$source = '/path/to/source/file.txt';
$destination = '/path/to/destination/file.txt';

if (copy($source, $destination)) {
    echo "File transferred successfully!";
} else {
    echo "Error transferring file.";
}
