本文实例讲述了PHP实现的随机IP函数。分享给大家供大家参考，具体如下：
function get_rand_ip(){
$arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","60","66","218","218","62","63","64","66","66","122","211");
$randarr= mt_rand(0,count($arr_1));
$ip1id = $arr_1[$randarr];
$ip2id= round(rand(600000, 2550000) / 10000);
$ip3id= round(rand(600000, 2550000) / 10000);
$ip4id= round(rand(600000, 2550000) / 10000);
return $ip1id . "." . $ip2id . "." . $ip3id . "." . $ip4id;
}
echo get_rand_ip();//输出：211.104.85.78
希望本文所述对大家PHP程序设计有所帮助。
