论坛直接使用珊瑚虫/纯真IP数据库 FOR PW7.5
1、打开 require 目录下的 postfunc.php ，找到（这部分代码不知道PW还有没有在用，改改也无妨）：function cvipfrom($ip,$txt=null){
if ($ip==Unknown) return Unknown;
$d_ip = explode(.,$ip);
if ($txt!=0.txt) {
$onlineip = $ip;
$ip = substr($ip,strpos($ip,.)+1);
$txt = $d_ip..txt;
$d_ip = $d_ip; $d_ip = $d_ip; $d_ip = $d_ip; $d_ip = ;
}
if ($db = @fopen(R_P.ipdata/.$txt,rb)) {
flock($db,LOCK_SH);
$f = $l_d = ;
$d = \"\\n\".fread($db,filesize(R_P.ipdata/.$txt));
$wholeIP = $d_ip...$d_ip...$d_ip;
$d_ip && $wholeIP .= ..$d_ip;
$wholeIP = str_replace(255,*,$wholeIP);
if (($s = strpos($d,\"\\n$wholeIP\\t\"))!==false) {
fseek($db,$s,SEEK_SET);
$l_d = substr(fgets($db,100),0,-1); fclose($db);
$ip_a = explode(\"\\t\",$l_d);
$ip_a && $ip_a .=.$ip_a;
return $ip_a;
}
$ip = d_ip($d_ip);
while (!$f && !$l_d && $wholeIP) {

return $f;
}
return Unknown;
}
替换为：

2、打开 lib 目录下的 iptable.class.php ，找到：

备注：其中$type=0;为IP库配置，1为纯真IP库，0为珊瑚虫IP库，请根据需要配置好IP数据库，为了避免消耗太多资源，建议使用珊瑚虫IP数据库。
3、清空论坛 ipdata目录，再下载最新珊瑚虫或纯真IP数据库上传到 ipdata 目录（用什么IP数据库就下载上传什么IP数据库）。
下载后别忘记忘记解压出IP数据库再上传。珊瑚虫IP数据库文件名为：CoralWry.Dat，纯真IP数据库文件名为：QQWry.Dat。
