如何用PHP打印所有网络接口？

$interfaces = getifaddrs();
foreach ($interfaces as $interface) {
    if ($interface->ifa_addr->sa_family == AF_INET) {
        echo "Interface: " . $interface->ifa_name . "\n";
        echo "IP Address: " . $interface->ifa_addr->sin_addr->s_addr . "\n";
    }
}

$interfaces = netifaces_interfaces();
foreach ($interfaces as $interface) {
    $addresses = netifaces_addresses($interface);
    foreach ($addresses as $address) {
        if ($address['family'] == 'AF_INET') {
            echo "Interface: " . $interface . "\n";
            echo "IP Address: " . $address['addr'] . "\n";
        }
    }
}
