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:

复制代码 代码如下:

<?php
/*
 * get location by sina ip interface
 *
 *              @soulteary 2013.04.14
 */
classip
{
    private $args=array();

        $this->args=self::init_args(func_get_args());
        $ip=self::getip();
 
        $ret=preg_match_all('/(\d+\.){3}\d+/i',$ip,$result);
        if(!$ret){
            returnfalse;
        }else{
            $result=$result[0];
        }

            }
