php - PHP数组逻辑

Question

如何设置具有布尔值或存储在其中的测试分数的主题数组？

如果有人在一门学科的每项测试中都取得高分，我会尝试展示金牌。

我希望我可以更清楚地提出这个问题，但这里有一些代码可以帮助阐明：

$resTestsQryStr = "SELECT TestID, Subject FROM Tests
                            WHERE " . $edstr . " AND " . $plstr . " AND " . $levelStr . " GROUP BY Subject";
$resTests = mysql_query($resTestsQryStr);

while ($rowT=mysql_fetch_array($resTests))
{
    $subject=$rowT['Subject'];    
    $tID=$rowT['TestID'];
    $resScore= mysql_query("SELECT Score FROM CompletedTests WHERE UserNum = '$userNum' AND TestID = '$tID'");
    $rowScore= mysql_fetch_array($resScore);      
        if ($rowScore['Score'] < 100){
            $medalWinArray[$subject]= false;
            break;
        }
        else    
            $medalWinArray[$subject]= true;
}

我认为应该这样做：

SELECT Subject, MIN(Score) >= 100 GoldMedal
FROM Tests t
JOIN Completed Tests c ON c.TestID = t.TestID
WHERE $edstr AND $plstr AND $level
AND c.userNum = '$userNum'
GROUP BY Subject
