RE: match only a-z or 0-9

[Timothy Johnson]

 
You've essentially already done it.  [a-z0-9] is a character class that
includes all characters within that range.  So something like this would
work:

if($string =~ /^[a-z0-9]$/){
  print "It's only letters and digits.\n";
}else{
  print "There's something else in there.\n";
}
