Question

我有3个表单，每个表单有3个无线电，但由于随机发生器，一次执行一个。如果我单击一个收音机，它将转到下一页，并将通过if else语句进行检查。现在我的问题是，当它得到答案并且它是正确的时，它将输出是。但是，我的另一个if else声明我的其他无线电执行。由于它没有回答，它认为它是错误的，所以输出没有。

这是我的代码：

<body>

    <?php 
        //Creating random numbers
        $rid = rand(1,3);
    ?> 




    <?php 


    if ($rid == 1){

echo "

这是一种更清洁的方法。在is_correct函数内部，它会检查$_POST中是否存在特定答案，如果是，则在答案正确时返回：

function is_correct()
{
    $answer = array(
        'answerOne' => 'A',
        'answer2' => 'B',
        'answer3' => 'C',
    );

    foreach ($answer as $k => $v) {
        if (array_key_exists($k, $_POST)) {
            return $v == $_POST[$k];
        }
    }

    return false;
}

if (is_correct()) {
    echo "yes";
} else {
    echo "no";
}

我的其他if else语句正在执行php
