If we wanted to pass raw image data we would pass the data the MIME type an empty parameter and false. These parameters are a little cumbersome. At this stage we need to create the message body. We need to do this before we can set up the message headers. We create the body as follows create message body body message- get We can then create the message headers with a call to Mail_mime s headers function create message headers from .get_real_name admin_user . . admin_user. hdrarray array From from Subject subject hdrs message- headers hdrarray Finally having set up the message we can send it.

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
