it happens anyway.

the 'program running in the background' is the mailer daemon.

When you invoke php mail() function all that does is validate the
addresses and queue the e-mail.

sendmail (or whatever) then forks to do the actual sending as a separate
process. (or not if you use the queue only functionality: In that case
the mail will get sent in the next queue run - maybe every hour typically)

Now making up an external file as the message body is trivial, but
making it an attachment is not.

But even fairly large attachments - 5-10MB - is not too hard. And won't
tie up php too much o for too long.
