Unique identifier for filenames

[dev]

Hi,
Is it possible to add a unique identifier to filenames when trying to save them?
If someone sent me "image.jpeg", and I get a new email with "image.jpeg", the old image.jpeg would be overwritten.
This is my code:

                    $name = $attachment->getFileName();
                    $data = $attachment->getData();
                    $mime = $attachment->getMimeType();
                    $size = $attachment->getSize();
                    $saved = $attachment->saveToDirectory($path);

I would like it to be for example: image37ad2d8e.jpeg

Here's a quick solution, some of these codes can be merged together. However, I wrote it out for simplicity when reading.

  // Information about the file and where to save it
$saveToDirectory = getcwd() . "\\attachments\\"; // Get's the current directory and folder attachments
$attachmentName = $attachment->getFileName();
$pathToSave = $saveToDirectory . $attachmentName;

$attachment->saveToDirectory($saveToDirectory); // Save the file here

// Renaming the file to a unqiue id name
$fileExt = (new SplFileInfo($fileName))->getExtension(); // Get the file extention
$newFileName =  uniqid() . "." . $fileExt; // Create a name for the file

$renameFilePath = $tmpdir . $newFileName;// Path to save the file

rename($pathToSave, $renameFilePath);
