Mail from another host

my question is

my site in flash in a host that do not support PHP.
So I got the idea to use a host that supports PHP to upload my movie with the formmail and the PHP file.
Dos it work? To load a SWF with a form from another host and use a PHP form that host to send an e-mail?

I’ve done that a few times with some of my sites

why not just get a host with php installed. you could even run it of your pc.
