Can PHP upload files to a remote file system?

Question

Yii

Good day!
With uploading files to the server, in principle, everything is clear. Well, something like this, for example, is done in Yii2

...
$imageFile->saveAs(Yii::getAlias('@webroot') . '/storage/img/' .....
...

But here local paths are registered!
Is it possible to somehow upload files to a remote file system, for example, when the storage is physically located on another server?
Is it resolved?
Sincerely.
