Look in "mastering regular expressions" if You´re in doubt. There´s an example [^1-6] meaning if a digit between 1 and 6 is not in the value checked, it´s true: $var1 = "123"; $var2 = "789"; if(ereg("[^1-6]", $var1)) print "$var1 is true"; else print "$var1 is false"; returns false if(ereg("[^1-6]", $var2)) print "$var2 is true"; else print "$var2 is false"; returns true It´s untested though :-) -- Med venlig hilsen / best regards ComX Networks A/S Kim Madsen Systemudvikler/systemdeveloper -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
