Question

到目前为止，我的代码如下：

    static function get_parties_zipcode_and_radius($ZIPCODE_, $RADIUS_)
    {
        // get coordinates
        $google_json = json_decode(file_get_contents("http://maps.googleapis.com/maps/api/geocode/json?address=" . $ZIPCODE_ . "&sensor=false"), true);
        $lat = $google_json["results"][0]["geometry"]["location"]["lat"];
        $lng = $google_json["results"][0]["geometry"]["location"]["lng"];

        // query coordinates
        $query = "SELECT ID, ( 3959 * acos( cos( radians($lat) ) * cos( radians( lat ) ) 
            * cos( radians( lng ) - radians($lng) ) + sin( radians($lat) ) * sin(radians(lat)) ) ) AS distance 
            FROM PARTIES 
            HAVING distance < 25 
            ORDER BY distance 
            LIMIT 0 , 20;";
        $db = $GLOBALS['DB']->query($query);
        $db->execute();
        $db->bind_result($ID);
        $result = array();
        while ($db->fetch())
        {
            array_push($result, $ID);
        }
        $db->close();
        return $result;
    }

我收到错误：

Fatal error: Uncaught Error: Call to a member function execute() on boolean in /var/www/html/Party/lib/Party.php:244 Stack trace: #0 /var/www/html/Party/lib/Party.php(256): Party::get_parties_zipcode_and_radius('98683', '3') #1 {main} thrown in /var/www/html/Party/lib/Party.php on line 244

我从这里获得了基于坐标查询数据库的代码：MySQL Great Circle Distance (Haversine formula)

我无法将其整合到mysqli格式中。我更习惯于已经折旧的旧版mysql，我不确定如何转换。应该是一个直接的解决方案，我认为。

如何在此距离查询中使用mysqli
