PHP查询QQWry.dat通过IP获取地址信息
使用PHP对QQWry查询得到地址，可以使用户在浏览器上就能查询：PHP查询的代码可以直接参考Discuz项目：
http://code.google.com/p/discuz-renren-connect/
在function_misc.php里；
下面是查询函数代码：
function convertip_full($ip, $ipdatafile) {
if(!$fd = @fopen($ipdatafile, 'rb')) {
return '- Invalid IP data file';
}
$ip = explode('.', $ip);
$ipNum = $ip * 16777216 + $ip * 65536 + $ip * 256 + $ip;
if(!($DataBegin = fread($fd, 4)) || !($DataEnd = fread($fd, 4)) ) return;
@$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 = $ip2num = $ip1num = 0;
$ipAddr1 = $ipAddr2 = '';
$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 '- System Error';
}
$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 '- System Error';
}
$DataSeek = implode('', unpack('L', $DataSeek.chr(0)));
fseek($fd, $DataSeek);
$ipData2 = fread($fd, 4);
if(strlen($ipData2) < 4) {
fclose($fd);
return '- System Error';
}
$ip2num = implode('', unpack('L', $ipData2));
if($ip2num < 0) $ip2num += pow(2, 32);
if($ip2num < $ipNum) {
if($Middle == $BeginNum) {
fclose($fd);
return '- Unknown';
}
$BeginNum = $Middle;
}
}
$ipFlag = fread($fd, 1);
if($ipFlag == chr(1)) {
$ipSeek = fread($fd, 3);
if(strlen($ipSeek) < 3) {
fclose($fd);
return '- System Error';
}
$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 '- System Error';
}
$ipFlag = fread($fd, 1);
if($ipFlag == chr(2)) {
$AddrSeek2 = fread($fd, 3);
if(strlen($AddrSeek2) < 3) {
fclose($fd);
return '- System Error';
}
$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 '- System Error';
}
$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 == '') {
$ipaddr = '- Unknown';
}
return '- '.$ipaddr;
}
调用处需要传入要查询的IP地址和数据文件的路径，函数返回查询的结果；
所以再写一个调用的页面：
