this is working fine : if (eregi("^-?([1-3])+$",$x) echo "x is 1 or 2 or 3";
i forgot to say that doesnt work with 1-20 :( how to do it ?
if (preg_match('/^(20|1[0-9]|1-9])$/', $candidate)) {
// $candidate is a decimal integer between 1 and 20 inclusive with
no leading zeros.
}
/^(1?[1-9]|[12]0)$/ works too. The first part covers 1-9, 11-19; the second part gets you 10 and 20.
Plus, it's ever so slightly shorter! And isnt' that what's most important? :P
