Question

我需要能够添加到我的$ questions数组中，但代码中没有动态，所以当我添加一些东西时，我必须为每个问题创建一个if语句和一个新的输入字段来存储数据（老师要求以隐藏式存储）。有谁知道我如何才能提高效率？

<?php 




    date_default_timezone_set('Europe/Oslo');

    $questions = array(
        array(
            'text' => 'Whats your name?',
            'type' => 'text',
            'name' => 'svar1'
        ),
        array(
            'text' => 'Do you live in Oslo?',
            'type' => 'checkbox',
            'name' => 'checkbox'
        ),
        array(
            'text' => 'How old are you?',
            'type' => 'text',
            'name' => 'svar3'
        ),
        array(
            'text' => 'Do you have friends?',   
            'type' => 'text',
            'name' => 'svar4'
        ),
        array(
            'text' => 'Do you like going to the movies?',   
            'type' => 'text',
            'name' => 'svar5'
            )
    );




    $step = isset($_POST['step']) ? $_POST['step'] : 0;

    if (isset($_POST['prev'])) {
        $step --;
    }


    if (isset($_POST['svar1'])) {
        $step++;
    }



    echo "<p><a href='/webutvikling/oblig2.php?reset=true'>Start på nytt</a></p>\n";
?>
