PHP實現(xiàn)的隨機IP函數(shù)(國內(nèi)IP段)

    本文實例講述了PHP實現(xiàn)的隨機IP函數(shù)。分享給大家供大家參考，具體如下：
    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();//輸出：211.104.85.78
    希望本文所述對大家PHP程序設計有所幫助。
