php在html中写循环,将Html代码放在php循环之间

我在php中有一个while循环,并希望在它们之间放置radion按钮.像这样的东西:

$sql = "SELECT * FROM questions WHERE `type` IN

('".implode("','",$fin_element)."')";

$result = $conn->query($sql);

echo "check 1";

if ($result->num_rows > 0) {

// output data of each row

while($row = $result->fetch_assoc()) {

echo "check 3";

echo "Q:" . $row["question_name"]. "
";

echo "am i visible?";

$result = $conn->query($sql);

echo "id: " .$result->fetch_assoc()["answer1"]. "
";

?>

$result = $conn->query($sql);

echo "id: " .$result->fetch_assoc()["answer2"]. "
";

?>

$result = $conn->query($sql);

echo "id: " .$result->fetch_assoc()["answer3"]. "
";

?>

$result = $conn->query($sql);

echo "id: " .$result->fetch_assoc()["answer4"]. "
";

?>

}

} else {

echo "0 results";

}

?>

但这里的代码来自

• to

不起作用

实际上我正在做一个从数据库中提取问题和答案的测验问题,这里fin_element分别包含了获取问题的id列表,所以一次应该提取多个问题与答案.请帮忙.
