Getting list IPs from CIDR notation in PHP

Question

Is there a way (or function/class) to get the list of IP addresses from a CIDR notation?

For example, I have 73.35.143.32/27 CIDR and want to get the list of all IP\

Answer 1

I come up with a better idea

$ip_from= long2ip(ip2long($ip)& (-1<<(32-$net_mask)));
$ip_to= long2ip(ip2long($ip)| (~(-1<<(32-$net_mask))));

P.S:$ip is a ipv4 address like 60.12.34.5;$net_mask is a int net mask like 25;

it's very fast because of the bit shift operation
