本篇文章为大家展示了利用PHP怎么对地理位置进行获取，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

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();

    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$result;
                returntrue;
            }else{
                return$result;
            }
        }else{

            $apiURL='http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$result[0];
            if(isset($this->args['FORMAT'])&&$this->args['FORMAT']=='JSON'){
                $apiURL.='&format=json';
                $return=$this->ipCURL($apiURL);
            }else{
                $return=$this->ipCURL($apiURL);
                $return=iconv("GBK//IGNORE","UTF-8",$return);
            }

            if(isset($this->args['ECHO'])&&$this->args['ECHO']==true){
                echo$return;
                returntrue;
            }else{
                return$return;
            }

        }

    }

    public functioninit_args($args)
    {
        $result=array();
        for($i=0,$n=count($args);$i<$n;$i++){
            $result=self::associative_push($args[$i],$result);
        }
        return$result;
    }

    public functionassociative_push($arr,$tmp)
    {
        if(is_array($tmp)){
            foreach($tmpas$key=>$value){
                $arr[$key]=$value;
            }
            return$arr;
        }
        returnfalse;
    }

    public functionGetIP()
    {
        if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])&&$_SERVER['HTTP_X_FORWARDED_FOR']&&strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'],'unknown')){
            return$_SERVER['HTTP_X_FORWARDED_FOR'];
        }elseif(isset($_SERVER['REMOTE_ADDR'])&&$_SERVER['REMOTE_ADDR']&&strcasecmp($_SERVER['REMOTE_ADDR'],'unknown')){
            return$_SERVER['REMOTE_ADDR'];
        }
    }

    private functionipCURL($url)
    {
        $ch=curl_init();
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_HEADER,0);
        ob_start();
        curl_exec($ch);
        curl_close($ch);
        $result=ob_get_contents();
        ob_end_clean();
        return$result;
    }
}
