I want to scan the variables passed from teh url of my script for non alpha
characters. The variables should only consist of a-z A-Z 0-9 and spaces,
full stops and commas (Basically I don't want scripts to be passed via the
variable to the server)
I've used perl a long time ago and its regular expressions seemed ideal for
this kind of thing. Can enybody suggest a scrip to remove unwanted
characters from my variable?
