【问题描述】：
我找了又找，还是很迷茫。我挣扎的是一些基础知识，但我通常很擅长从例子中找出问题。
我需要帮助：我似乎无法根据我的 MySQL 查询填充高尔夫记分卡 HTML 表。不管出于什么原因，我希望我知道，我桌子上的最后一个高尔夫球手得到了所有的价值。我想不出我们的数据正确循环的方法。在第 9 洞，循环应该停止并移动到下一个高尔夫球手的下一行。
我一直在尝试 Whiles 和 Foreach 循环来弄清楚它们是如何工作的，这就是我同时拥有这两个循环的原因。一旦我弄清楚了单独的输出，我计划将这两个查询合并为一个。
我非常感谢任何指南。几周以来，我一直在寻找解决方案，但我意识到自己陷入了困境。
PHP PDO 查询
//Get Hole Info
$holeSQL = $auth_user->runQuery("SELECT HoleNum, FrontBack FROM `tblHole`
WHERE CourseID=:course_id AND FrontBack=:front_back ORDER BY
`tblHole`.`HoleNum` ASC");
$holeSQL ->
execute(array(":course_id"=>$courseID,":front_back"=>$frontback));
//Get Par Info
$parSQL = $auth_user->runQuery("SELECT Par FROM `tblHole` WHERE
CourseID=:course_id AND FrontBack=:front_back ORDER BY `tblHole`.`HoleNum`
ASC");
$parSQL ->
execute(array(":course_id"=>$courseID,":front_back"=>$frontback));
//Get Round Scores
$scoresSQL = $auth_user->runQuery("SELECT tblScore.PlayerID, tblScore.RoundID, tblScore.HoleNum, tblScore.NumStrokes, tblScore.NumPutts, tblScore.FIR, tblScore.GIR FROM tblScore WHERE RoundID=53 ORDER BY tblScore.PlayerID ASC");
$scoresSQL -> execute(array(":round_id"=>$roundID));
$scores = $scoresSQL -> fetchALL(PDO::FETCH_ASSOC);
$Scores 的数组输出

【问题讨论】：
-
你在哪里设置
$scores？ -
这里没有将
$scores设置为foreach ($arr as $userInfo)中特定玩家的分数。所以每次循环都是一样的。 -
感谢您的来电。我添加了对 $scores 的查询。我还删除了我原来的 2 数组，因为它们与我的问题无关。我添加了查询 $scores 时得到的数组的一部分。 @Barmar
-
为什么
$scoresSQL需要加入tblUsers？它从不使用该表中的任何内容。以及为什么它不使用任何聚合函数时使用GROUP BY？ -
我看不出为什么
$scores只包含playerID = 2的分数。查询中没有任何内容将其限制为特定玩家。
