PHP中實現(xiàn)獲取IP和地理位置類分享

更新時間：2015年02月10日 10:27:41 投稿：junjie

這篇文章主要介紹了PHP中實現(xiàn)獲取IP和地理位置類分享,本文地理定位使用的是SINA的通用接口,需要的朋友可以參考下

發(fā)現(xiàn)之前有一個腳本沒有寫完，簡單擴(kuò)充了一下。
獲取IP使用的是經(jīng)典的邏輯，地理定位使用的是SINA的通用接口。

使用方法詳見源碼：

<?php

/*

 * GET LOCATION BY SINA IP INTERFACE

 *

 *              @SOULTEARY 2013.04.14

 */

classIP

{

    private $args=array();

    function__construct()

    {

        $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];

        }

        if(isset($this->args['ONLYIP'])&&$this->args['ONLYIP']==true){

            if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){

                $result=json_encode($result);

            }else{

                $result=implode(',',$result);

            }

            if(isset($this->args['ECHO'])&&$this->args['ECHO']==true){

                echo$result;

                returntrue;
