PHP’s method of obtaining the IP corresponding to the region and using the network type

This article mainly introduces the method of PHP obtaining the IP corresponding to the region and using the network type. The example analyzes PHP by calling Tips for obtaining IP and network type from ip138 database. Friends who need it can refer to it

The example in this article describes how PHP obtains the IP corresponding region and uses the network type. Share it with everyone for your reference. The specific analysis is as follows:

During the test here, because the ip168 website was banned, I tried to modify the original code to use the data call of the ip138 database. The code is as follows:

//原程序有问题，现修改为ip138数据库

/**

* 获取IP地区

* Enter description here ...

* @param unknown_type $ip

function GetArea($ip){

$url = "http://www.ip138.com/ips8.asp?ip=".$ip."&action=2";

$contents = file_get_contents($url);

preg_match_all('|

本站主数据：.*

|',$contents,$rsR);

$rsR[0][0] = str_replace("

本站主数据：", "", $rsR[0][0]);

$pos = strpos($rsR[0][0],'

');

$Area = substr_replace($rsR[0][0],'',$pos);

return $Area;

}

header('Content-type:text/html;Charset=gb2312');

$area = GetArea('218.242.232.194');

print_r($area);

//There is a problem with the original program, now it is modified to ip138 database /** * Get IP region * Enter description here ... * @param unknown_type $ip */ function GetArea($ip){ $url = "http://www.ip138.com/ips8.asp?ip=".$ip."&action=2"; $contents = file_get_contents($url); preg_match_all('|

Main data of this site: .*

|',$contents,$rsR); $rsR[0][0] = str_replace("

Master data of this site:", "", $rsR[0][0]); $pos = strpos($rsR[0][0],'

'); $Area = substr_replace($rsR[0][0],'',$pos); return $Area; } header('Content-type:text/html;Charset=gb2312'); $area = GetArea('218.242.232.194'); print_r($area); ?>
