emlog系统存储了评论人的IP地址,有的时候,需要显示该IP的真实地理地址,可以通过以下两种方法获得。
一、本地获得IP地理地址。通过本地查找本地IP数据库(纯真版)来获得,IP数据库可以到http://www.cz88.net/下载安装后,在安装目录里把qqwry.dat文件提取出来,放到emlog根目录即可。 (保证与index.php同在一个目录中)
在module.php中添加以下代码:
<?php
//获取IP地理地址
$data = '254.254.254.254';
class IpLocation {
var $fp;
var $firstip;
var $lastip;
var $totalip;
function getlong() {
$result = unpack('Vlong', fread($this->fp, 4));
return $result['long'];
}
function getlong3() {
$result = unpack('Vlong', fread($this->fp, 3).chr(0));
return $result['long'];
}
function packip($ip) {
return pack('N', intval(ip2long($ip)));
}
function getstring($data = "") {
$char = fread($this->fp, 1);
while (ord($char) > 0) {
$data .= $char;
$char = fread($this->fp, 1);
}
return $data;
}
function getarea() {
$byte = fread($this->fp, 1);
switch (ord($byte)) {
case 0:
$area = "";
break;
case 1:
case 2:
fseek($this->fp, $this->getlong3());
$area = $this->getstring();
break;
default:
$area = $this->getstring($byte);
break;
}
return $area;
}
function getlocation($ip) {
if (!$this->fp) return null;
$location['ip'] = gethostbyname($ip);
$ip = $this->packip($location['ip']);
$l = 0;
$u = $this->totalip;
$findip = $this->lastip;
while ($l <= $u) {
$i = floor(($l + $u) / 2);
fseek($this->fp, $this->firstip + $i * 7);
$beginip = strrev(fread($this->fp, 4));
if ($ip < $beginip) {
$u = $i - 1;
}
else {
fseek($this->fp, $this->getlong3());
$endip = strrev(fread($this->fp, 4));
if ($ip > $endip) {
$l = $i + 1;
}
else {
$findip = $this->firstip + $i * 7;
break;
}
}
}
fseek($this->fp, $findip);
$location['beginip'] = long2ip($this->getlong());
$offset = $this->getlong3();
fseek($this->fp, $offset);
$location['endip'] = long2ip($this->getlong());
$byte = fread($this->fp, 1);
switch (ord($byte)) {
case 1:
$countryOffset = $this->getlong3();
fseek($this->fp, $countryOffset);
$byte = fread($this->fp, 1);
switch (ord($byte)) {
case 2:
fseek($this->fp, $this->getlong3());
$location['country'] = $this->getstring();
fseek($this->fp, $countryOffset + 4);
$location['area'] = $this->getarea();
break;
default:
$location['country'] = $this->getstring($byte);
$location['area'] = $this->getarea();
break;
}
break;
case 2:
fseek($this->fp, $this->getlong3());
$location['country'] = $this->getstring();
fseek($this->fp, $offset + 8);
$location['area'] = $this->getarea();
break;
default:
$location['country'] = $this->getstring($byte);
$location['area'] = $this->getarea();
break;
}
if ($location['country'] == " CZNET") {
$location['country'] = "未知";
}
if ($location['area'] == " CZNET") {
$location['area'] = "";
}
return $location;
}
function IpLocation($filename = "qqwry.dat") {
$this->fp = 0;
if (($this->fp = @fopen($filename, 'rb')) !== false) {
$this->firstip = $this->getlong();
$this->lastip = $this->getlong();
$this->totalip = ($this->lastip - $this->firstip) / 7;
register_shutdown_function(array(&$this, '_IpLocation'));
}
}
function _IpLocation() {
if ($this->fp) {
fclose($this->fp);
}
$this->fp = 0;
}
}
function getaddress($myip){
$ipOrDomain=$myip;
$iplocation = new IpLocation();
$location = $iplocation->getlocation($ipOrDomain);
$address=mb_convert_encoding($location['country'].$location['area'], "utf-8", "gbk");
return $address;
}
?>
然后在需要显示的地方插入:
<?php echo getaddress($comment['ip']);?>
即可。
二、通过远程网站相关接口实现。
在module.php中添加以下代码:
<?php
//blog:获取IP地址所在地,提取新浪IP接口
function getaddress($ip)
{
//调用sina查询接口
$str = file_get_contents("http://counter.sina.com.cn/ip?ip=".$ip);
//转换字符集
$str = mb_convert_encoding($str,"UTF-8","GBK");
//匹配结果
preg_match_all('/[\x{4e00}-\x{9fa5}]+/u',$str,$get);
//将数组转换成字符串
$add = implode('-',$get[0]);
//返回结果
return $add;
}
?>
然后在需要显示的地方插入:
<?php echo getaddress($comment['ip']);?>
即可。
图片显示方式:
<a title= <?php echo getaddress($comment['ip']);?>> <img src="./content/templates/default/images/ip.png"></a>
其中ip.png这个图标会显示在评论人的后面,图片自找,鼠标放上去会显示地理地址。
另一种方法显示IP:
1.首先在当前模板的module.php最后添加如下代码:
<?php
function convertip($ip) {
$dat_path = EMLOG_ROOT.'/content/templates/你的模板文件/QQWry.Dat'; //*数据库路径*//
if(!$fd = @fopen($dat_path, 'rb')){
return 'IP数据库文件不存在或者禁止访问或者已经被删除!';
}
$ip = explode('.', $ip);
$ipNum = $ip[0] * 16777216 + $ip[1] * 65536 + $ip[2] * 256 + $ip[3];
$DataBegin = fread($fd, 4);
$DataEnd = fread($fd, 4);
$ipbegin = implode('', unpack('L', $DataBegin));
if($ipbegin < 0) $ipbegin += pow(2, 32);
$ipend = implode('', unpack('L', $DataEnd));
if($ipend < 0) $ipend += pow(2, 32);
$ipAllNum = ($ipend - $ipbegin) / 7 + 1;
$BeginNum = 0;
$EndNum = $ipAllNum;
while($ip1num>$ipNum || $ip2num<$ipNum) {
$Middle= intval(($EndNum + $BeginNum) / 2);
fseek($fd, $ipbegin + 7 * $Middle);
$ipData1 = fread($fd, 4);
if(strlen($ipData1) < 4) {
fclose($fd);
return '系统出错!';
}
$ip1num = implode('', unpack('L', $ipData1));
if($ip1num < 0) $ip1num += pow(2, 32);
if($ip1num > $ipNum) {
$EndNum = $Middle;
continue;
}
$DataSeek = fread($fd, 3);
if(strlen($DataSeek) < 3) {
fclose($fd);
return '系统出错!';
}
$DataSeek = implode('', unpack('L', $DataSeek.chr(0)));
fseek($fd, $DataSeek);
$ipData2 = fread($fd, 4);
if(strlen($ipData2) < 4) {
fclose($fd);
return '系统出错!';
}
$ip2num = implode('', unpack('L', $ipData2));
if($ip2num < 0) $ip2num += pow(2, 32);
if($ip2num < $ipNum) {
if($Middle == $BeginNum) {
fclose($fd);
return '未知';
}
$BeginNum = $Middle;
}
}
$ipFlag = fread($fd, 1);
if($ipFlag == chr(1)) {
$ipSeek = fread($fd, 3);
if(strlen($ipSeek) < 3) {
fclose($fd);
return '系统出错!';
}
$ipSeek = implode('', unpack('L', $ipSeek.chr(0)));
fseek($fd, $ipSeek);
$ipFlag = fread($fd, 1);
}
if($ipFlag == chr(2)) {
$AddrSeek = fread($fd, 3);
if(strlen($AddrSeek) < 3) {
fclose($fd);
return '系统出错!';
}
$ipFlag = fread($fd, 1);
if($ipFlag == chr(2)) {
$AddrSeek2 = fread($fd, 3);
if(strlen($AddrSeek2) < 3) {
fclose($fd);
return '系统出错!';
}
$AddrSeek2 = implode('', unpack('L', $AddrSeek2.chr(0)));
fseek($fd, $AddrSeek2);
} else {
fseek($fd, -1, SEEK_CUR);
}
while(($char = fread($fd, 1)) != chr(0))
$ipAddr2 .= $char;
$AddrSeek = implode('', unpack('L', $AddrSeek.chr(0)));
fseek($fd, $AddrSeek);
while(($char = fread($fd, 1)) != chr(0))
$ipAddr1 .= $char;
} else {
fseek($fd, -1, SEEK_CUR);
while(($char = fread($fd, 1)) != chr(0))
$ipAddr1 .= $char;
$ipFlag = fread($fd, 1);
if($ipFlag == chr(2)) {
$AddrSeek2 = fread($fd, 3);
if(strlen($AddrSeek2) < 3) {
fclose($fd);
return '系统出错!';
}
$AddrSeek2 = implode('', unpack('L', $AddrSeek2.chr(0)));
fseek($fd, $AddrSeek2);
} else {
fseek($fd, -1, SEEK_CUR);
}
while(($char = fread($fd, 1)) != chr(0)){
$ipAddr2 .= $char;
}
}
fclose($fd);
if(preg_match('/http/i', $ipAddr2)) {
$ipAddr2 = '';
}
$ipaddr = "$ipAddr1 $ipAddr2";
$ipaddr = preg_replace('/CZ88.Net/is', '', $ipaddr);
$ipaddr = preg_replace('/^s*/is', '', $ipaddr);
$ipaddr = preg_replace('/s*$/is', '', $ipaddr);
if(preg_match('/http/i', $ipaddr) || $ipaddr == '') {
$ipaddr = '未知';
}
$ipaddr = iconv('gbk', 'utf-8//IGNORE', $ipaddr);
if( $ipaddr != ' ' )
return $ipaddr;
else
$ipaddr = '评论者来自火星,无法或者其所在地!';
return $ipaddr;
}
?>
然后再在评论中添加要你要显示位置。原作者未给出图片提示的代码。
纯文字显示代码:
<?php echo convertip($comment['ip']); ?>
图片title显示代码:
<img src="<?php echo BLOG_URL; ?>XXX/ip.png" alt="<?php echo convertip($comment['ip']); ?>" title="<?php echo convertip($comment['ip']); ?>" width="16" height="16" class="useragent" data-bd-imgshare-binded="1">
上面代码中的XXX/ip.png是图片路径
其中使用到的纯真数据库以及图片自己下载,本博主暂不提供。
