PDO，如何查看4个不同表中的选定数据，然后使用PHP在网页上查看它

Question

我正在为学校创建一个小项目。我已经能够创建一个完成工作查询的函数（使用SQL测试）。

我得到的错误是;注意：尝试在第34行的E：\ programs \ XAMPP \ htdocs \ Esports \ View \ Tournament.php中获取非对象的属性'tournamentName'。

但是我为他们所有人做到了这一点？不知道为什么。

如果有人可以提供帮助，我将不胜感激。

我的代码如下。

我的DataAccess.php运行查询的函数是;

function getAllTourament()
{
    global $pdo; 
    $statement = $pdo ->prepare (' SELECT tournament.tournamentName,
    tournament.console,
    tournament.no_of_players,
    tournament.prize,
    game.gName,
    sponsors.sponsorName,
    venue.venue_name,
    venue.venue_location,
    venue.venue_date,
    venue.venue_time
FROM tournament, game, sponsors, venue
    WHERE tournament.gameID = game.gameID AND tournament.sponsorID = sponsors.sponsorID AND tournament.venueID = venue.venueID
    ORDER by tournament.tournamentName, console, no_of_players, prize , gName , sponsorName , venue_name,venue_location, venue_date, venue_time');
    $statement->execute();
     $result = $statement;
    return $result;   
}
