Passing variables to PHP from procmail f

[Anon]

Hi,

I'd like to write a script to maintain a mailing list -- basic subscribe and unsubscribe to start with.

If I capture the variables from the subject line:
1) subscribe
2) unsibscribe

and the reply to header, how do I pass those variables to a php script.

Procmail filter would look something like:

:0:
^{To.majordomo
Subject.(subscribe|unsubscribe)}
REPLYTO_=formail -cXReply-To: | head -1 | formail -rtzxTo:
{
:0 c
| [e-mail]

:0
| /home/username/public_html/mailing_list.php

}
