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?
