Procmail and Variables and PHP

Hello all,

I am work with a script that uses formail to break down the email into its 
parts :
        :0h
        RP=|formail -zxReturn-Path:
        :0h
        MID=|formail -zxMessage-Id:
        :0h
        xsender="|formail -zxX-Sender:"
        :0h
        xmailer=|formail -zxX-Mailer:
        :0h
        DATE=|formail -zx Date:
        :0h
        to=|formail -zxTo:
        :0h
        from=|formail -zxFrom:
        :0h
        mime_vers=|formail -zxMime-Version:
        :0h
        content_type=|formail -zxContent-Type:
        :0h
        SUBJECT=|formail -zxsubject:
        :0B
        BODY=|formail -I ""

what i need to do is ensure that the variables are self 
containing.  IE:  RP="info about RP" like put into brackets or quotes or 
something so that when i echo out RP in php it is seen as "info about RP" 
and not info.
Better yet have procmail replace all spaces " " with an underscore "_"


please help!
