PHP通过IP 获取 地理位置(实例代码)

发布:JB02 ? 来源:脚本学堂?

分享一例php代码,实现通过IP地址获取访问者的地理位置,在php编程中经常用到,有需要的朋友参考下吧。本节内容:PHP通过IP获取地理位置

例子:
?

复制代码代码示例:

//取得访问者的物理地址
function get_client_dizhi($ip){

$doc = new DOMDocument();
$doc->load('http://www.youdao.com/smartresult-xml/search.s?type=ip&q='.$ip); //读取xml文件
$humans = $doc->getElementsByTagName( "smartresult" ); //取得humans标签的对象数组
foreach( $humans as $human )
{
$names = $human->getElementsByTagName( "product" ); //取得name的标签的对象数组
$name = $names->item(0)->nodeValue; //取得node中的值,如
$sexs = $human->getElementsByTagName( "location" );
$sex = $sexs->item(0)->nodeValue;
}
return $sex;

}
//获取IP地址
// 获取客户端IP地址
function get_client_ip(){
?? if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
?????? $ip = getenv("HTTP_CLIENT_IP");
?? else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
?????? $ip = getenv("HTTP_X_FORWARDED_FOR");
?? else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
?????? $ip = getenv("REMOTE_ADDR"); // www.jbxue.com
?? else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
?????? $ip = $_SERVER['REMOTE_ADDR'];
?? else
?????? $ip = "unknown";
?? return($ip);
}

$ip=get_client_ip();
$dizhi=get_client_dizhi($ip);

附,新浪、有道、腾讯的Ip地址查询接口。

How does garbage collection work for PHP sessions?How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AM

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

How can you trace session activity in PHP?How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AM

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

How can you use a database to store PHP session data?How can you use a database to store PHP session data?Apr 27, 2025 am 12:02 AM

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
