Plaseplease update... 5.1.6 is from 2006! I read the "it's required",
but I can't imagine _anything_ that it's worth it to use such an
extremely outdated, unsupported and therefore insecure and inefficient
version... You know: There are 3 (!) new minor versions available right
now (5.2, 5.3 and 5.4).
However: Regarding your concrete problem I guess you can use ip2long()
if (ip2long($ip)) {
} else {
}

Hello:
I want to use filter_var function by this way:
$ip = "192.168.0.1";
if( !filter_var($ip, FILTER_VALIDATE_IP) )
{
echo "IP is not valid";
}
else
{
echo "IP is valid";
}
I want to check the string $ip is IP address or not.but my PHP version is
5.1.6.
and I know the filter_var requires at least PHP version 5.2.0.
so, Any other function in PHP 5.1.6 can slove this work and replace the
filter_var function ?
Thank you, I'm a new one, so I don't know much about PHP documentation.
By the way, The PHP version is required. so I can't upgrade it.
