Shouldn't it be [0-9] for each of the elements, also?
What if I want to put 123.012.123.123 or something similar?

RE: [PHP-DB] Valid IP
Take out those + in your regular expression and it works fine for me,
for any format.

Try this:
function padIP($ip){
$ar = explode(".",$ip);
$ip = "";
$xt = "";

Hello guys
I know this should be asked in another list but don't want to subcribe just
for a simple question. I apologise in advance if that bothers anyone.
I'm trying to check valid IPs that come from a form filled by a user so I'm
using the following:
function valid_ip($ip)
{
//Check whether it is a valid IP
if (ereg("^[1-9]{2,3}+\.[1-9]{2,3}+\.[1-9]{2,3}+\.[1-9]{2,3}+$", $ip))
return true;
else
return false;
}
However it just accepts IPs such as xxx.xxx.xxx.xxx Errors arise whith IP
such as xxx.xx.xxx.xxx that is every part of the IP should be 3 numbers
lenght to be accepted making the function not very handy.
Any idea?
