  • PHP中实现获取IP和地理位置类分享

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){ 
  24.  
  25.             if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){ 
  26.                 $result=json_encode($result); 
  27.             }else{ 
  28.                 $result=implode(',',$result); 
  29.             } 
  30.             if(isset($this->args['ECHO'])&&$this->args['ECHO']==true){ 
  31.                 echo$result; 
  32.                 returntrue; 
  33.             }else{ 
  34.                 return$result; 
  35.             } 
  36.         }else{ 
  37.  
  38.             $apiURL='http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$result[0]; 
  39.             if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){
