Need email auto-forward PhP script asap similar to this code

I need a PhP script written that can use code like below, to forward a name and email address to a 3rd party email provider (Awebwer) We used to have this working, but the script was lost b/c I no longer own that company / server. Here is the example script: <img width="1" height="1" alt="" src="[login to view URL][[billing first name]]&amp;email=[[billing email]]&amp;body=This is a test message&amp;subject=Testing Sale Notification&amp;recipients=EMAIL1,EMAIL2 /> Whereas: 1. I need a new php script written like the one here: [login to view URL] 2. But that we can upload to our new server 3. That will accept the parameters in the path above, and be able to forward them to multiple email addresses. 4. One will be an email provider (Aweber) that will add them to a list and send an email confirmation 5. By adding additional email addresses separated by commas, it can also send receipt emails to admins 6. Email 1, and Email2 above would be actual email addresses that the script forwards the user variables / information to. Need this done in next 1-2 hours, but should simple for someone with experience.
