Hi gang:
While we're discussing what's legal in css, here's a couple of things
I've found about sessions.
I found that starting a session with a number doesn't work.
$myvar = $_SESSION['1myvar'];
I also found that dumping a session to a variable with the same name
may cause problems, such as:
> $myvar = $_SESSION['myvar'];
Regardless of what anyone may say to the contrary, it doesn't work
everywhere. I found that out the hard way. The fix is simply to use a
different name for the variable, such as:
$my_var = $_SESSION['myvar'];
Hopes this help someone.
Cheers,

The second case won't work if you have register globals turned on I
believe, as it will attempt to create $_SESSION['myvar'] as $myvar. I
believe that RG might have something to do with the first as well. I
seem to remember a thread a while back talking about sessions not being
able to use numbered indexes because they are a special super global.

You are right, but here's the rub -- when you have register globals
turned on and you use:
$myvar = $_SESSION['myvar'];
This sometimes works and sometimes fails. I had an entire site where
I had been using the same names for attributes and variables
throughout and suddenly one page didn't work. All other pages worked
just fine, but this single page didn't.
I searched high and low for an answer and found a vague reference
where someone else had run into a similar problem and found the
solution was to change the variable name. So I did with that single
page and everything worked.
Why did that single page not work and everything else did? I haven't
a clue, but I will say that I reduced the problem to that
specifically and that *was* the problem.
Additionally, why was that problem not realized in the other pages on
the same site -- I don't know, but this was an example of "sometimes
it works, and sometimes it doesn't" -- a heck of a way to run a
railroad.
