php和js實現(xiàn)根據(jù)子網(wǎng)掩碼和ip計算子網(wǎng)功能示例

?php
$ip = '192.168.6.1';
$mask = '255.255.2.0';
$sub_net = array();//子網(wǎng)
$ip_explode = explode('.', $ip);
$mask_explode = explode('.', $mask);
foreach ($ip_explode as $key => $ip_num) {
  $sub_net[] = (int)$ip_num  (int)$mask_explode[$key];
}
$sub_net = implode('.', $sub_net);
echo $sub_net;

script>
var ip = '192.168.6.1';
var mask = '255.255.255.0';
var sub_net = [];//子網(wǎng)
var ip_explode = ip.split('.');
var mask_explode = mask.split('.');
  console.log('ip_explode='+ip_explode);
  console.log('mask_explode='+mask_explode); for (var i = 0, num = ip_explode.length; i  num; i++) {
  c = parseInt(ip_explode[i])  parseInt(mask_explode[i]);
  console.log('c='+c);
  sub_net.push(c);
}
sub_net = sub_net.join('.');
console.log(sub_net);
