Tedd, Adam,
Thank you for your advice. While I'm very grateful for your advice,
unfortunately, it seems that the core of what you suggest do not fit
my situation.
First, with Adam's suggestion that I use <br /> instead of <p>. The
output I am generating is akin to what csszengarden.com generates,
so that I can have complete CSS control over page layout and style.
<br /> tags are limited in their scope of design control as compared
to <p> tags, so they are insufficient.
Second, with Tedd's advice that I place the variable without
formatting within the HTML code. I apologize if I was unclear, as I
seem to have given you the wrong impression. I am absolutely trying
to separate content from design, which is why everything the user
stores is in plain text, and all the formatting happens when it is
displayed. None of the modifications which add HTML to the variable
get put back into the database.
The only small formatting consideration that does get stored in the
database are the simulated tags (eg: --++ for <h3>). I'm not totally
thrilled about letting users create some formatting with simulated
tags, but the trade off is for giving the users more flexibility.
I'm following the same model as WikiMedia, SMF Forums, and other PHP
based user input interfaces. And I am trying to be more strict and
less expansive than they are.
I really am grateful for your advice, but it seems that I really do
need to find a way to create <p> tags around the text when it is
displayed.
But I definitely thank you for giving me something to think about,
and also the tips on how to make my code more efficient.
It's my hope that someone can still steer me towards the ability to
get <p> tags surrounding paragraphs, and to be able to separate <h3>
and other tags from within those <p> tags.

Dave:
If you want to go that way, then I suggest that you place a "preview"
page for the poster. Most people don't want to post something that's
all screwed up and will take the time to fix it IF they are given the
chance.
That way, the only real problem you have to deal with is what happens
when someone enters something that isn't correct.
I might also suggest that there are functions that will help you sort
out acceptable html from unacceptable html.
For example, strip_tags($text, '<p>'); will allow both <p> and </p>
tags, but will prohibit everything else.
If you want a more complete answer to your problem, you can use
regular expressions to extract and manipulate tags, but it's complex.
A good read, and what appears to be a solution, can be found on pages
153-159 of PHP String Handling Handbook by Matt Wade et al published
by Wrok (ISBN 1-86100-835-X) in 2003.
I've looked for the download support files they claim to have, but found none.

I've contacted one of the authors, let's see if he provides the code.
If he does, I'll send it to you.
hth's.
