Isaac,
Yes, but it it not recommended. If you are really sure you want to do
this, i'll give you a hint; you want to 'extract' the values of the post
array. If you go this route, please make sure you have read and
understood the warning(s) in the function documentation and followed the
recommended precautions.
In reality though this is generally not a good idea, and almost as bad
as setting on register globals.
Carl.
