// Create a boundary string.  It needs to be unique (not in the text) so ...
// We are going to use the sha1 algorithm to generate a 40 character string:

// Read in our file attachment
$attachment = file_get_contents('attachment.zip');

// Base64 encode it so that the potentially binary file can safely be send
// over email, which is a text based protocol.
