php - 我如何检查包含 ip 地址(inet_aton)的 php 变量($stat_ip)是否位于两个 ip(inet_aton 格式)的范围内

Question

//变量 $stat_ip 位于表 Hasoffers 中，要检查它是否位于列值 network_start_ip 和 network_end_ip 之间，后者位于另一个名为 Blacklisted 的表中。我需要编写一个函数来帮助我做同样的事情通过访问所有三个。

 <?php
        include('adodb/adodb.inc.php');
        mysql_connect("*****","***","***");
        mysql_select_db("********");
        $pl=mysql_query("SELECT stat_ip,stat_session_ip FROM Hasoffers");
        $count=mysql_num_rows($pl)

            while($row=mysql_fetch_array($pl))
              {
               $stat_ip=$row['stat_ip'];

               echo fn($stat_ip)."<br>";
              }

          $bip=mysql_query("SELECT inet_aton(network_start_ip),inet_aton(network_end_ip) FROM blacklisted");

          while($array=mysql_fetch_array($bip))
          {
            $start_ip=$array['network_Start_ip'];
            $end_ip = $array['netwrok_end_ip'];

          }


          function fn($stat_ip)
             {
                $result =mysql_query('SELECT stat_ip FROM Hasoffers where ($stat_ip BETWEEN INET_ATON(network_start_ip) AND INET_ATON(network_end_ip)');





        }
        ?>php

你可以在

之间使用

SELECT inet_aton(network_start_ip),inet_aton(network_end_ip) 
FROM blacklisted
WHERE your_ip_column  BETWEEN INET_ATON(network_start_ip) AND INET_ATON(network_end_ip)

如果您需要在单个选择中同时进行查询，您可以在两者之间使用左连接

SELECT a.stat_ip 
FROM Hasoffers as a 
LEFT JOIN blacklisted on  as b on inet_aton(a.stat_ip)  
              between INET_ATON(b.network_start_ip) AND INET_ATON(b.network_end_ip)
