Thanks to you both for the suggestions...
My internet access is limited at the moment but I will test this in a
few hours (when I have my LAMP machine)...
However... I'm curious, the solutions provided, when used with
preg_replace, would replace any of those characters, as opposed to
replace anything BUT those characters... (ie I want to replace anything
that is NOT alphanumeric or an underscore with a nospace...)
Thanks again for the help,
Randell D.
