ip城市定位新浪接口：

/**
         * 新浪ip 地址获取城市信息
         */
        //根据ip 地址获取所在城市信息
    	function getIPLoc_sina($queryIP){
    		$url = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$queryIP;
    		$ch = curl_init($url);
    		curl_setopt($ch,CURLOPT_ENCODING ,'utf8');
    		curl_setopt($ch, CURLOPT_TIMEOUT, 5);
    		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回
    		$location = curl_exec($ch);
    		$location = json_decode($location);
    		curl_close($ch);
    		$loc = "";
    		if($location===FALSE) return "";

    			$loc = $location->province.$location->city.$location->district.$location->isp;		}else{
    			$loc = $location->desc;
    		}
    		return $loc;
    	}

ip地址 ip138 地址查询：
