MultiPart E-Mail Code for PHP (Text and HTML)

Whilst trawling through some of my ultra-old posts on various forums I’ve found this nifty little piece of code that enables you to send in both HTML and TEXT form. This is useful for clients that cant display HTML (they will display the text instead). I developed it back in 2007 so it may need updating but its a useful bit of code!
UPDATE: Peter Mills recently emailed me with a problem with this script and compatability with gmail, I have managed to fix this. It seems that gmails parser has gotten even more strict, there were stray line breaks where there shouldnt have been and the initial boundary declaration in the headers was not wrapped properly in double quotes! Cheers for finding this bug Peter and hopefully its all working again now!

 CHANGES:
 -- Is Now Compatible With GMail
 -- Encrypts Messages In Base64 For Easier Transportation
 -- 03/11/09 - Changed to work with changes in GMail, removed now unnecessary base64 encoding
 NOTES:
 -- From experience with different mail services i've discovered some key pointers
 when sending html or any type of email:
  * DO NOT link to external CSS stylesheets, most of the time these are either filtered out
  or do not load properly
  * As discovered in GMail it strips out any stylesheets completely, even inline ones so you're
  going to have to use the style='' tags on any div's etc you want to make look pretty
  * Bear in mind linking to any external resources will bring up a warning on the clients
  end and they can choose to or not to load external resources.
  * Keep HTML resources as simple as possible, most of the time they aren't loaded as well as
  they would in firefox and so can be really mucked up if you do some complicated magic with
  them.
 COMING SOON:
 -- Will be turned into a class making it easier to send emails :)
