一、打开include\misc.php开头查找
- if(!defined('IN_DISCUZ')) {
- exit('Access Denied');
- }
复制代码
下边加
- define('QQWRY' , $qqwry_root_path . 'ipdata/wry.dat' ) ;
- function IpToInt($Ip) {
- $array=explode('.',$Ip);
- $Int=($array[0] * 256*256*256) + ($array[1]*256*256) + ($array[2]*256) + $array[3];
- return $Int;
- }

- }

- {

- }
- return $str ;
- }
- function qqwry ($dotip) {

- $ip = IpToInt ( $dotip );
- $this->fp= @fopen(QQWRY, "rb");

- }

- }

- else

- }
- $this->getStartIp ( $RangB ) ;

- if ( ( $this->StartIp <= $ip ) && ( $this->EndIp >= $ip ) ){
- $nRet = 0 ;
- $this->getCountry ( ) ;
-
- $this->Local = str_replace("(我们一定要解放台湾!!!)", "", $this->Local);
- }else {
- $nRet = 3 ;
- $this->Country = '未知' ;
- $this->Local = '' ;
- }
- fclose ( $this->fp ) ;
- return $nRet ;
- }
- }
复制代码
二、查找
- function convertip($ip) {
- $datadir = DISCUZ_ROOT.'./ipdata/';
- $ip_detail = explode('.', $ip);
- if(file_exists($datadir.$ip_detail[0].'.txt')) {
- $ip_fdata = fopen($datadir.$ip_detail[0].'.txt', 'r');
- } else {
- if(!($ip_fdata = fopen($datadir.'0.txt', 'r'))) {
- echo 'Invalid IP data file';
- }
- }
- for ($i = 0; $i <= 3; $i++) {
- $ip_detail[$i] = sprintf('%03d', $ip_detail[$i]);
- }
- $ip = join('.', $ip_detail);
- do {
- $ip_data = fgets($ip_fdata, 200);
- $ip_data_detail = explode('|', $ip_data);
- if($ip >= $ip_data_detail[0] && $ip <= $ip_data_detail[1]) {
- fclose($ip_fdata);
- return $ip_data_detail[2].$ip_data_detail[3];
- }
- } while(!feof($ip_fdata));
- fclose($ip_fdata);
- return 'UNKNOWN';
- }
复制代码
改为:
- function convertip($ip) {
- $wry = new TQQwry ;
- $nRet = $wry->qqwry ( $ip );
- return $wry->Country.$wry->Local ;
- }
复制代码
三、把QQ纯真IP数据文件QQwry.dat改名为wry.dat,上传ipdata目录。OK了。
