下面是如何使用选择来完成此操作的示例。我认为单选按钮在这里会更好。

<form method="POST" action="questions.php">
            <p>1.Question1?</p>
    <p>
        <select name="questions[1]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <p>2.Question2?</p>
    <p>
        <select name="questions[2]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <p>3.Question3?</p>
    <p>
        <select name="questions[3]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <p>4.Question4?</p>
    <p>
        <select name="questions[4]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <p>5.Question5?</p>
    <p>
        <select name="questions[5]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <p>6.Question6?</p>
    <p>
        <select name="questions[6]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    7.Question7?
    <p>
        <select name="questions[7]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    8.Question8?
    <p>
        <select name="questions[8]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    9.Questione9?
    <p>
        <select name="questions[9]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    10.Question10?
    <p>
        <select name="questions[10]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    11.Question11?
    <p>
        <select name="questions[11]">
            <option value="YES">YES</option>
            <option value="NO">NO</option>
        </select>
    </p>
    <input name="submit" type="submit" value="submit" />
</form>

然后在 PHP 端进行处理...(我也不确定你的条件如何工作，这是一种可以完成的方法。)

foreach($_POST['questions'] as $key => $question) {
        switch($key) {
            case 1:
            case 2:
            case 3:
            case 5:
            case 6:
                if($question == 'YES') {
                    echo 'the answer A';
                } else {
                    echo 'the answer C';
                }
            break;
            case 4:
            case 7:
            case 8:
            case 9:
            case 10:
            case 11:
                if($question == 'YES') {
                    echo 'the answer B';
                } else {
                    echo 'the answer C';
                }
            break;
        }
    }

输出:

Question #1=YES<br />Question #2=NO<br />Question #3=NO<br />Question #4=NO<br />Question #5=NO<br />Question #6=NO<br />Question #7=NO<br />Question #8=NO<br />Question #9=NO<br />Question #10=NO<br />Question #11=NO<br />
