我设法在问题后面显示相应的选项，并在底部显示一个提交按钮。
在单击提交按钮时，如何获得用户为从数据库中循环输出的每个问题所选择的值?ans1, ans2等
这对于比较他们的答案和答案键并计算他们的分数是必要的。
。请帮助!非常感谢你和更多的权力!
为每个单选输入指定一个值，更新后的脚本可以是:
$host = 'localhost';
$user = 'root';
$pw = '';
$db = 'pmdb';
mysql_connect($host,$user,$pw);
mysql_select_db($db);
$result = mysql_query("SELECT * FROM Questions WHERE QuizID=1");
$num_rows = mysql_num_rows($result);
while($row = mysql_fetch_assoc($result))
{
$array[] = $row;
}
//Start the form
echo "<form method='"post'" action='"path/to/receiving.php'">'n";
for($i=0; $i<=($num_rows-1); $i++)
{
//Render a question + the answer choices
echo $array[$i]['Title']."<br />'n";
for ($j=1;$j<=4;$j++) {
echo "<input type='"radio'" name='"answers$i'" value='"$j'">".
$array[$i]['Answer'.$j]."<br />'n";
}
}
//End the form
echo "<input type='"submit'" value='"submit'" id='"submit'">'n</form>";
现在从PHP中读取答案的值:
echo $_POST["answers1"];
//The answer given for question 1, will be between
// 1-4 or null (if they didn't answer
