If the error you are getting is something like:
PHP Notice: Undefined variable: showMessage on line 100 script x.php

Have a look at this (http://uk2.php.net/error_reporting) for info on how to
change the error reporting level at runtime (or more permanently) to
something less strict than the default. However its supposed to be good
practice to define all your variables... not that I could be accused of
doing it all the time!

Hope that helps

Subject: [thelist] Setting PHP variables...

Hi all...
I'm on site this week and working on a project that the server has Global
Variables turned off(I know I know, I SHOULD be doing that by
default..!)

Anyhoo, When I needed something dynamic, I simply did:
if (isset($_SESSION["userId"])) {
  $showMessage = "welcome";
}

However on this server, I was getting error messages stating that the
variable was not set.

If I added a blank variable at the top of the code ' $showMessage = "";  '
that 'fixed' the big.
However, now I have a list of about 30 variables at the top of my code and
it looks untidy.
There must be a better way to say to the server:
if I asign a value to a variable, presume it exists.

This only occurs when the main page requests a variable (eg $showMessage )
and it's not ben asigned..
on other servers, it has just simply shown nothing, cause nothing was
found...

Am I being a tool?
