The result obtained by an IP address is not perfect. The reason is that the IP address resolution of ip138 is not very detailed in dealing with foreign addresses, so I re-wrote a code using Chianz.com, the instance code is as follows:

The code is as follows:

<? Php
$ IpAddr = "4.4.44.4 ";
$ IpChinazAddr = "http://tool.chinaz.com/IP? IP = ". $ ipAddr;
$ Contents = file_get_contents ($ ipChinazAddr );
$ Pattern = "/=>. +
/";
$ String = $ contents;
Preg_match_all ($ pattern, $ string, $ addrArray );
$ Num = count ($ addrArray [0]);
$ Pattern = "/(==>>). + (==>> s )/";
For ($ I = 0; $ I <$ num; $ I ++ ){
$ AddrArray [0] [$ I] = preg_replace ($ pattern, "", $ addrArray [0] [$ I]);
}
Echo"

";  
print_r($addrArray);  
echo "

";
?>
