PHP gets the program code of the region based on IP_PHP tutorial

First use php to get the local IP, and then use php’s curl function to get the user’s detailed area. Let’s take a look at the code;

The code is as follows

/*
* This function is to obtain the client and IP

代码如下

/*  * 这个函数是获取客户端和IP  */ function GetIP() {  if(!empty($_SERVER["HTTP_CLIENT_IP"]))  {   $cip = $_SERVER["HTTP_CLIENT_IP"];  }  else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))  {   $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];  }  else if(!empty($_SERVER["REMOTE_ADDR"]))  {   $cip = $_SERVER["REMOTE_ADDR"];  }  else  {   $cip = '';  }  preg_match("/[d.]{7,15}/", $cip, $cips);  $cip = isset($cips[0]) ? $cips[0] : 'unknown';  unset($cips);  return $cip; }

*/
function GetIP()
{
if(!empty($_SERVER["HTTP_CLIENT_IP"]))
{
$cip = $_SERVER["HTTP_CLIENT_IP"];
}
else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
{
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
else if(!empty($_SERVER["REMOTE_ADDR"]))
{
$cip = $_SERVER["REMOTE_ADDR"];
}
else
{
$cip = '';
}
preg_match("/[d.]{7,15}/", $cip, $cips);
$cip = isset($cips[0]) ? $cips[0] : 'unknown';
unset($cips);
return $cip;
}

Method 1, using the QQWry.Dat IP library, we only have chubby

Use the simple method.

Usage example

Example 1:

代码如下
$IpLocation = new IpLocation(); $client = $IpLocation->getlocation(); print_r($client);

The code is as follows
$IpLocation = new IpLocation(); $client = $IpLocation->getlocation(); print_r($client);

Example 2:

代码如下
$IpLocation = new IpLocation('../qqwry/QQWry.Dat'); $client = $IpLocation->getlocation('115.148.101.72'); print_r($client);

The code is as follows
$IpLocation = new IpLocation('../ qqwry/QQWry.Dat'); $client = $IpLocation->getlocation('115.148.101.72'); print_r($client);

The specific IP library and Iplocation class files are not introduced here. Let’s search them on Baidu.

Method 2, use api interface

Example 1,

The code is as follows

/**
* Get IP area
* Enter description here ...
* @param unknown_type $ip
​*/
function GetArea($ip){

代码如下
/**   * 获取IP地区   * Enter description here ...   * @param unknown_type $ip   */  function GetArea($ip){  $url = "http://ip168.com/ip/?ip=".$ip;  $contents = file_get_contents($url); // preg_match_all('/)/',$contents,$rs);  preg_match_all('| 本站主数据：.* |',$contents,$rsR);  $rsR[0][0] = str_replace(" 本站主数据：", "", $rsR[0][0]);  $rsR[0][0] = str_replace(" ", "", $rsR[0][0]);  return $rsR[0][0];  }

$url = "http://ip168. com/ip/?ip=".$ip;
$contents = file_get_contents($url);
// preg_match_all('/)/',$contents,$rs);
preg_match_all('|

Main data of this site: .*

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

Main data of this site:", "", $rsR[0][0]);
$rsR[0][0] = str_replace("

", "", $rsR[0][0]);
return $rsR[0][0];
}

Example 2,

The following function uses PHP’s curl function to obtain detailed regions from the Internet

代码如下
function lazdf($ip){ $curl= curl_init(); curl_setopt($curl,CURLOPT_URL,"http://www.ip138.com/ips138.asp?ip=".$ip); curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); $ipdz=curl_exec($curl); curl_close($curl); preg_match("/ (.*?) /i",$ipdz,$jgarray); preg_match("/本 www.111cn.net 站主数据：(.*)/i", $jgarray[1],$ipp); return  " 欢迎来自 ".$ipp[1]." 的朋友！ "; } echo lazdf(GetIP());//输出ip

The code is as follows

function lazdf($ip){ $curl= curl_init(); curl_setopt($curl,CURLOPT_URL,"http: //www.ip138.com/ips138.asp?ip=".$ip); curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); $ipdz=curl_exec($curl); curl_close($curl); preg_match("/ (.*?) /i",$ipdz,$jgarray); preg_match("/this www.111cn.net website owner data: (.*)/i", $jgarray[1],$ipp); return "       Welcome from ".$ipp[1 ]." Friends! "; } echo lazdf(GetIP());// Output ip
