这篇文章主要介绍了php实现的随机ip函数,可实现输出国内ip段的功能,涉及php字符串与数组的计算操作相关技巧,需要的朋友可以参考下
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
