这篇文章主要介绍了PHP中实现获取IP和地理位置类分享,本文地理定位使用的是SINA的通用接口,需要的朋友可以参考下

发现之前有一个脚本没有写完，简单扩充了一下。

获取IP使用的是经典的逻辑，地理定位使用的是SINA的通用接口。

使用方法详见源码：

1. <?php 
2. /* 
3.  * GET LOCATION BY SINA IP INTERFACE 
4.  * 
5.  *              @SOULTEARY 2013.04.14 
6.  */ 
7. classIP 
8. { 
9.     private $args=array(); 
10.  
11.     function__construct() 
12.     { 
13.         $this->args=self::init_args(func_get_args()); 
14.         $ip=self::GetIP(); 
15.  
16.         $ret=preg_match_all('/(\d+\.){3}\d+/i',$ip,$result); 
17.         if(!$ret){ 
18.             returnfalse; 
19.         }else{ 
20.             $result=$result[0]; 
21.         } 
22.  
23.         if(isset($this->args['ONLYIP'])&&$this->args['ONLYIP']==true){
