我知道我的问题标题不清楚，我会在这里解释。
这里有四个单选按钮，每个问题都有四个答案。问题是每个问题都应该有随机答案选项
正确答案将包含值=1。
Q1这是问题1？
<input type ="radio" value="1" />
<input type ="radio" value="2" />
<input type ="radio" value="3" />
<input type ="radio" value="4" />
Q2这是问题2？
<input type ="radio" value="2" />
<input type ="radio" value="4" />
<input type ="radio" value="1" />
<input type ="radio" value="3" />
如何生成随机选项？
我正在使用PHP并从数据库中获取选项值。
使用PHP，您可以创建一个包含所有可能值的数组，然后对其进行后缀：
$vals = [1, 2, 3, 4];
shuffle ($vals);
for ($i = 0; $i < count ($vals); $i++) : ?>
<input type="radio" value="<?php echo $vals[$i] ?>" />
<?php endfor ?>
每次需要新的随机值时，都可以再次调用shuffle。
select * from your_table order by rand()
E X A M p L E
数据库：
TABLE: question
id question
1 what is..
2 when did..
3 Which one..
TABLE: answer
id question_id answer_options correct
1 1 answer 1 0
2 1 answer 2 1
3 1 answer 3 0
4 1 answer 4 0
查询：
Question loop STARTS
# Use the question_id to loop through the below
$query = "SELECT * FROM answer where question_id='$question_id' order by rand()";
$qr = mysqli_query($con, $query);
if (mysqli_num_rows($qr) > 0)
{
$count = 2;
while ($res = mysqli_fetch_object($qr))
{
if ($res->correct == 1)
$value = 1;
else
$value = $count++;
echo '<input type="radio" value="'.$value.'" /> '.$res->answer_options;
}
}
Question loop ENDS
