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，以这种形式(一个while循环(是获取它们的最快方法。当我这样做时，它看到所有单选按钮都在同一个"组"中。如何使它有多个"组"，以便可以回答多个问题？

我尝试向其添加div，但这不起作用。

<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GROUP它们，则需要像这样name标签上添加索引：

$i = 0;
while ($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++;
}

我使用$i作为索引，我认为如果你使用for loop会更好，因为它已经具有$key价值，我认为在while使用它是一个坏习惯。
