PHP query ip location (province, city)_PHP tutorial

The article introduces the use of relevant api interfaces to obtain a php instance in the city and region based on the client IP address. Let's take a look.

Today I will share a small PHP program that obtains the location based on the client IP address. I wrote it before and have been using it for a long time. I feel that this interface is still stable. Although there are many similar ones on the Internet, I think mine is still very good. The core code can be implemented in only 3 lines. Although the function is not very powerful, it is enough for our daily use. Here is the code:

The code is as follows  代码如下 复制代码       图1 ： 返回数据     图2 ： 查询成功   如果喜欢的话，可以试试，几行代码就能搞定，我觉得还是挺实用的！！ 本文章来源于 代潇瑞博客 原文地址：http://www.daixiaorui.com/read/3.html   请输入ip地址：   //获取ip地址 //$ip = $_SERVER['REMOTE_ADDR']; //自动获取客户端的IP //ip对应的地区 if(!empty($_POST['ip'])){ $ip = $_POST['ip']; //接口地址,这样返回的是一个xml结果集，如图1; $str = file_get_contents("http://www.yodao.com/smartresult-xml/search.s?type=ip&q=".$ip); //这里要得到里面的地址信息，提取xml方法有很多，我用的是正则。 preg_match_all( "/(.*?)/",$str,$addr1);   //最终结果，如图2;   $addr = $ip."=>".$addr1[1][0];   echo $addr;  } ?>

Copy code

If you like it, you can try it. It can be done with a few lines of code. I think it is quite practical! ! This article comes from Dai Xiaorui’s blog. Original address: http://www.daixiaorui.com/read/3.html

Please enter the ip address:

<🎜> //Get IP address <🎜> <🎜> //$ip = $_SERVER['REMOTE_ADDR']; //Automatically obtain the client’s IP<🎜> <🎜> //Region corresponding to IP<🎜> <🎜> if(!empty($_POST['ip'])){<🎜> <🎜> $ip = $_POST['ip'];<🎜> <🎜> //Interface address, this returns an xml result set, as shown in Figure 1; <🎜> <🎜> $str = file_get_contents("http://www.yodao.com/smartresult-xml/search.s?type=ip&q=".$ip);<🎜> <🎜> //To get the address information inside, there are many ways to extract xml. I use regular expressions. <🎜> <🎜> preg_match_all( "/(.*?)/",$str,$addr1); //Final result, as shown in Figure 2; $addr = $ip."=>".$addr1[1][0]; echo $addr; } ?> Figure 1: Return data Figure 2: Query successful If you like it, you can try it.
