Use Sina IP library to obtain IP detailed address

使用新浪IP库获取IP详细地址

class Tool{
    /**
 * Get the IP ownership (Sina IP library)
 *
 * @param $ip String IP address: 112.65.102.16
 * @return Array

        $ipJson = self::httpCurl($link);
        preg_match("/"country":"(.*)"/Uis",$ipJson, $match1);
        preg_match("/"province":"(.*)"/Uis",$ipJson, $match2);
        preg_match("/"city":"(.*)"/Uis",$ipJson, $match3);
        return array(

    {
        $curl_handle = curl_init();

        curl_close($curl_handle);
        return $file_content;
    }

    /**

    static public function ucode2zh($code)
    {

        $rslt = array();

        foreach($temp as $k => $v)
        {
            $v = hexdec($v);
            $rslt[] = '' . $v . ';';
        }

        $r = implode('',$rslt);
        return empty($r) ? $code : $r;
    }
}

获取IP地址类使用实例

$ipStr = Tool::getIpCity('112.65.102.16');
print_r($ipStr);

# 返回结果
Array ( [country] => 中国 [province] => 上海 [city] => 上海 )
