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;
        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?
