php用IP查询归属地

Posted 2023-05-15

php用IP查询归属地，现在网上搜索一看的话都在用QQwryIP库。
想知道的是这个库准吗？
还有类似这样的库吗？
推荐个最准的库吧，谢谢。

还有想了解用IP查询国家的方法。
这是怎么获取的？？
每个国家都有规律的吗？？
高手们请指教。

参考技术A class ip_location

function init()

$this->wrydat = 'ip_area.dat';

$this->fp = fopen($this->wrydat, 'rb');

$this -> REDIRECT_MODE_1 = 1;
$this -> REDIRECT_MODE_2 = 2;


function get($str)

return $this->$str;


function set($str,$val)

$this->$str = $val;


function getbyte($length,$offset=null)

!is_null($offset) && fseek($this->fp, $offset, SEEK_SET);

return fread($this->fp, $length);


function packip($ip)

return pack('N', intval(ip2long($ip)));


function getlong($length=4, $offset=null)

$chr=null;
for($c=0;$length%4!=0&&$c<(4-$length%4);$c++)

$chr .= chr(0);

$var = unpack( 'Vlong', $this->getbyte($length, $offset).$chr);
return $var['long'];


function getwryversion()

$length = preg_match("/coral/i",$this->wrydat)?26:30;
$this->wrydat_version = $this->getbyte($length, $this->firstip-$length);


function getipnumber()

$this->firstip = $this->getlong();
$this->lastip = $this->getlong();
$this->ipnumber = ($this->lastip-$this->firstip)/7+1;


function getstring($data='', $offset=NULL)

$char = $this->getbyte(1,$offset);
while(ord($char) > 0)

$data .= $char;
$char = $this->getbyte(1);

return $data;


function iplocaltion($ip)

$ip = $this->packip($ip);
$low = 0;
$high = $this->ipnumber-1;
$ipposition = $this->lastip;
while($low <= $high)

$t = floor(($low+$high)/2);
if($ip < strrev($this->getbyte(4,$this->firstip+$t*7)))
$high = $t - 1;
else

if($ip > strrev($this->getbyte(4,$this->getlong(3))))
$low = $t + 1;
else

$ipposition = $this->firstip+$t*7;
break;



return $ipposition;


function getarea()

$b = $this->getbyte(1);
switch(ord($b))

case $this -> REDIRECT_MODE_0 :
return '';
break;
case $this -> REDIRECT_MODE_1:
case $this -> REDIRECT_MODE_2:
return $this->getstring('',$this->getlong(3));
break;
default:
return $this->getstring($b);
break;



function getiplocation($ip)

$ippos = $this->iplocaltion($ip);
$this->ip_range_begin = long2ip($this->getlong(4,$ippos));
$this->ip_range_end = long2ip($this->getlong(4,$this->getlong(3)));
$b = $this->getbyte(1);
switch(ord($b))

case $this -> REDIRECT_MODE_1:
$b = $this->getbyte(1,$this->getlong(3));
if(ord($b) == $this -> REDIRECT_MODE_2)

$countryoffset = $this->getlong(3);
$this->area = $this->getarea();
$this->country = $this->getstring('',$countryoffset);

else

$this->country = $this->getstring($b);
$this->area = $this->getarea();

break;
case $this -> REDIRECT_MODE_2:
$countryoffset = $this->getlong(3);
$this->area = $this->getarea();
$this->country = $this->getstring('',$countryoffset);
break;

$this->country = $this->getstring($b);
$this->area = $this->getarea();
break;

调用方法:

$iploca = new ip_location;
$iploca -> init();
$iploca -> getiplocation($ip);

$area['country'] = str_replace(array('CZ88.NET'), '', $iploca -> get('country'));
$area['area'] = str_replace(array('CZ88.NET'), '', $iploca -> get('area'));

$area['country']=='' && $area['country']='未知';
$area['area']=='' && $area['area']='未知';
return $area;本回答被提问者采纳
