是否可以像这样检查多个单选按钮？

Question

我从我的数据库中回显单选按钮的值，并且以这种形式（while 循环）是获取它们的最快方法。当我这样做时，它会看到所有单选按钮都在同一个“组”中。如何使它具有多个“组”以便可以回答多个问题？我尝试向它添加一个 div ，但没有奏效。<form action="Antwoord.php" method="POST"><?php   $sql = "SELECT * FROM  questionlist_choice";   $result = mysqli_query($conn, $sql);  if ($result->num_rows > 0) {  while ($row = mysqli_fetch_assoc($result)) {$vraag = $row['Vraag'];$vraagA = $row['Vraag_keuzeA'];$vraagB = $row['Vraag_keuzeB'];$vraagC = $row['Vraag_keuzeC'];$vraagD = $row['Vraag_keuzeD'];$vraagE = $row['Vraag_keuzeE'];$vraagF = $row['Vraag_keuzeF'];echo "<div>";    echo "<br><p>$vraag</p>";    echo "<input type='radio' name='gender' value='$vraagA'> $vraagA<br>";    echo "<input type='radio' name='gender' value='$vraagB'> $vraagB<br>";    echo "<input type='radio' name='gender' value='$vraagC'> $vraagC<br>";    echo "<input type='radio' name='gender' value='$vraagD'> $vraagD<br>";    echo "<input type='radio' name='gender' value='$vraagE'> $vraagE<br>";    echo "<input type='radio' name='gender' value='$vraagF'> $vraagF<br>";echo "</div>";  }}?><input type="submit"></form>

抱歉，我不太了解您的问题，但是如果您想要GROUP他们，您需要在name标签上添加索引，如下所示：

$i = 0;

while ($row = mysqli_fetch_assoc($result)) {

   $vraag = $row['Vraag'];

   $vraagA = $row['Vraag_keuzeA'];

   $vraagB = $row['Vraag_keuzeB'];

   $vraagC = $row['Vraag_keuzeC'];

   $vraagD = $row['Vraag_keuzeD'];

   $vraagE = $row['Vraag_keuzeE'];

   $vraagF = $row['Vraag_keuzeF'];

   echo "<div>";

   echo "<br><p>$vraag</p>";

   echo "<input type='radio' name='gender[$i]' value='$vraagA'> $vraagA<br>";

   echo "<input type='radio' name='gender[$i]' value='$vraagB'> $vraagB<br>";

   echo "<input type='radio' name='gender[$i]' value='$vraagC'> $vraagC<br>";

   echo "<input type='radio' name='gender[$i]' value='$vraagD'> $vraagD<br>";

   echo "<input type='radio' name='gender[$i]' value='$vraagE'> $vraagE<br>";

   echo "<input type='radio' name='gender[$i]' value='$vraagF'> $vraagF<br>";

   echo "</div>";

$i++;

}

我$i用作索引，我认为如果您使用它会更好，for loop因为它已经$key有价值，我认为使用它while是一个坏习惯。
