In your regex you have a "." this will match anything try this: <plaintext><?php function ValidateString($string) { if ( preg_match("/[^a-zA-Z0-9\_\.\' -]+/", $string) ) { return "Invalid Characters"; } return false; }

That "." is inside a character class where it is a literal character (matches only "."). Why are you backslashing the underscore is beyond me. This is fine, is there any harm in escaping them?

The match will work either way right?
