PHP中实现获取IP和地理位置类分享

前端技术 2023/09/07 PHP

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();
 
    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;
    }
}
