We begin by instantiating the class as follows create the actual sending object sender Mail factory mail The parameter mail here just tells the Mail class to use PHP s mail function to send messages. We could also use sendmail or smtp as the value for this parameter for the obvious results. Next we send the mail to each of our subscribers. We do this by retrieving and looping through each of the users subscribed to this list and using either the Mail send or regular mail depending on the user s MIME type preference Next 673 if subscriber 2 H send HTML version to people who want it sender- send subscriber 1 hdrs body else
