PHP - Attach multiple files to email, files attached are blank?!!? - php

Question

This is just a sample of the code, essentially I have a form with 4 files to upload. The files are successfully saved on my server in a designated folder. However, I obviously am not attaching them properly since they are empty....can anyone help?
Also, the attachments disply the directory name instead of the file name...what am I missing?
Many thanks!!!

I know it's not the answer to your post, but after struggling with this kind of problems in the past, I gave up and used PHPMailer. If you still want to roll your own, you should take a look at its source code.
