Does anybody know of a good way to make sure that a string contains ONLY
certain characters. I tried using
ereg("[~`!@#$%^&*(){}-+=|\\/.,<>'\":;\[\]]", $string); but I get parse
errors. Besides that I only want the characters A-Za-z0-9_ in $string. Is
there is simpler way to ensure this rather than checking to see if any of
the characters I don't want are in there?
Thank you for your help in advance.
