Just for the record, one more way of doing what you asked for is:
echo ${"trivia_answer_$correct_answer"};
But I totally agree with all the suggestions to use an array instead.
Cheers!

Thanks for the code sample - a little more complex than I've ever used. Can
you explain something for me?
The first "unset" line - what is it doing? If it is removing the item from
the $process array, then how can you then reference the value ($v) in the
very next line? I must be missing something.
Also - I don't see the need to be stripping slashes from the $k
(keys/indices?) elements. What am I missing there?
As I said - the lines are a something new to me and I may not be
interpreting what is going on here. Basically I see that you are processing
all of the arrays (GET,POST, etc) at once, doing each one in turn. For each
one, you then get down to the values returned to the script as a $k/$v pair
which you then check to see if it is in itself an array.(although you ask if
$v is an array, while I would have thought you'd ask if $k was an array).
Once you get to the basest element you remove the slashes.
Thanks again - still waiting on my host company to get back to me - they've
escalated the problem of not being able to turn the quotes off. Hmmm....

<?php

**************************
Thank you Richard for your effort, but I had the jist of all of this. What
I don't get is the points I asked about. Can you answer the questions I
mentioned?

I've got this error:
*"Fatal error*: Call to undefined method DOMElement::C14N() in..."
My local server has the version 2.7.6 of libxml, and works fine. The
development server has the version 2.6.26
DOM/XML API Version 20031129.
This may be the problem? Or there's a dependency lost? or something like
this...

hi again.
it look likes my code is ugly so no one wants to play with it :D.
rewrote the consumer and provider code using only the php provided
classes/methods. I have borrowed code from
http://www.lornajane.net/posts/2011/php-oauth-provider-request-tokens and
http://toys.lerdorf.com/archives/55-Writing-an-OAuth-Provider-Service.html.
still it's same "invalid signature" exception. This time it's in
localhost,consumer on port 3000 and provider on port 5000.
new consumer code http://pastebin.com/ndEhP8Rv and provider code
http://pastebin.com/SfdKu3nQ . it's my second week struggling with this
code. any help would be really appreciate.
