它只顯示一條消息，而不是選擇正確的消息來顯示

Question

我試圖確定正確回答的問題並正確回答問題。如果回答正確，則顯示「完全正確」，如果不正確則顯示「不正確」信息。問題無論是否正確，總是顯示該問題的答案不正確。

下面是代碼：

$check = true; 

    foreach ($studentData['questions'] as $questionId => $questionData) { 

      if($questionData['answer'] == $questionData['studentanswer']) 
    { 
     echo '<td width="30%" class="studentanswer green"><strong>'.htmlspecialchars($questionData['studentanswer']).'</strong></td>' . PHP_EOL; 
    } 
    else 
    { 
     echo '<td width="30%" class="studentanswer red"><strong>'.htmlspecialchars($questionData['studentanswer']).'</strong></td>' . PHP_EOL; 
     $check = false; 
    } 


if($check) 
{ 
    echo '<p class="green"><strong>Fully Correct</strong></p>'; 
} 
else 
{ 
    echo '<p class="red"><strong>Not Correct/Not Fully Correct</strong></p>'; 
} 

} 

Answer 1

此行再次設置爲true爲$check

if($questionData['answer'] == $questionData['studentanswer']) 
{ 
echo '<td width="30%" class="studentanswer green"><strong>'.htmlspecialchars($questionData['studentanswer']).'</strong></td>' . PHP_EOL; 
$check = true; 
} else
