Hi, I would use a regular expression to check it. This is a pretty general
one, but I think it should do the trick. It searches for 1 or more upper
or lowercase letters, followed by a literal dot, followed by 2 or 3
lowercase letters. Of course there are valid domains that would not match
this (foobar.co.uk) for example, but it should work with the values you
specified.
if (ereg("^[a-zA-Z]+\\.[a-z]{2,3}$", $var)) {
// valid domain
}
else{
// not valid
}
