在PHP中获取IP地址的最后两部分

Question

I'd like to get the two lasts octets from an IP address with PHP. I tried this :

substr(strrchr($ip,'.'),2);

But it seems I misunderstood the code, since it's not working... (eg. if my IP is 192.168.0.79, this line returns only "9"...)

Answer 1

you can explode the ip string and get the parts from it.

    $ip = "192.168.0.79";
    $split = explode(".", $ip);
    $part1 = $split[2]; // 0
    $part2 = $split[3];// 79
