How do I use webform tokens in my PHP code for the form submission page?
These won't show up in the results page.  I think these are only useable when the form is submitted.  One thing that confused me for a while was the [fieldset].  If the value you are trying to access is not in a fieldset it is [Root].

Name:  __

%value[Root][name]  would be most likely way to access that value after the form is submitted by the user.

(%email works also if you are going to send an email, but that also shows the label)

Hope this helps and is actually what you need help with.
