Or you could regex it with something like this:
ereg("^([^a-zA-Z0-9]*)(.*)$", $inStr, $resultArr);
Then $resultArr[0] will be the original input, $resultArr[1] will be
everything up until an unacceptable character was encountered (not including
the unaccepted character), and the last part would contain the unaccepted
character (first) along with the rest of the input. If you took the substr
for the first character of that, you would be able to say "The character
$bad_char is not allowed" (etc).
My syntax, etc might be a little off, I haven't tested this... but
theoretically it should work.....
