Can anyone suggest, with examples, how I might go about changing my protected tweet setting from False to True via PHP.
What I'd like to do is Switch my protected tweet status to: True, post a update and then switch it back to False.
I beleive the URL required is thus:
http://twitter.com/account/update_profile.xml
...
<protected>false</protected>
..
Bear in mind I am not the greatest at PHP :)

I don't think that is going to do what you want. Protection applies to your timeline (that is, all of your tweets), not each particular tweet. If you make your tweets protected, non-followers can't see them, but if you go back to unprotected, they can still everything you posted while you were protected.

authenticity_token=token you can grab from http://twitter.com/account/settings using DOM or regex user[protected]=1
