Question

首先，我是PHP的新手，之前只做了一些HTML / CSS，所以我对这些东西知之甚少。

我在学校接受了一项任务;创建使用的东西：

回声
HTML和PHP的组合
PHP中的变量
输入

我一直试图制作的是一个页面，您可以在其中选择今天的哪一天，按OK，然后会显示一条消息：“今天是$今天。因此，星期五之前有X天。” / p>

到目前为止我做了什么：

    <p>
        Temporary description with HTML <?php echo "<p> and PHP. </p>" ?>
    </p>

    <?php


        $ledestreng1;  
        $ledestreng2;  
        $ledestreng3;

        $ledestreng1 = "Today is ";  
        $ledestreng2 = " There is therefore ";
        $ledestreng3 = " days until friday."  



    ?>



    <form>
        <input type="radio" name="day" value="monday"> Monday<br>
        <input type="radio" name="day" value="tuesday"> Tuesday<br>
        <input type="radio" name="day" value="wednesday"> Wednesday<br>
        <input type="radio" name="day" value="thursday"> Thursday<br>
        <input type="radio" name="day" value="friday"> Friday<br>
        <input type="radio" name="day" value="saturday"> Saturday<br>
        <input type="radio" name="day" value="sunday"> Sunday<br>
        <input type="submit" name="submit" value="OK">
    </form>

    <?php
        if (isset($_POST[submit])){
        $today = $_POST[day];
        echo "<p>$ledestreng1 $today,$ledestreng2,$ledestreng3</p>";
        }     
      ?>

我从这里做什么？如何从收音机输入中选出一天，如何知道星期五之前的剩余天数？我认为if语句会起作用，比如“如果”周四“被选中，那就是”3天“，直到星期五。”

您对我如何做到这一点有什么建议吗？

HTML

<form method="POST">
    <input type="radio" name="day" value="monday"> Monday<br>
    <input type="radio" name="day" value="tuesday"> Tuesday<br>
    <input type="radio" name="day" value="wednesday"> Wednesday<br>
    <input type="radio" name="day" value="thursday"> Thursday<br>
    <input type="radio" name="day" value="friday"> Friday<br>
    <input type="radio" name="day" value="saturday"> Saturday<br>
    <input type="radio" name="day" value="sunday"> Sunday<br>
    <input type="submit" name="submit" value="OK">
</form>

PHP

<?php
if(isset($_POST['submit'])) {
    $day = $_POST['day'];

    if($day == "saturday") {
      echo "6 days untill it's friday";
    } elseif($day == "sunday") {
      echo "5 days untill it's friday";
    } elseif($day == "monday") {
      echo "4 days untill it's friday";
    } elseif($day == "tuesday") {
        echo "3 days untill it's friday";
    } elseif($day == "wednesday") {
        echo "2 days untill it's friday";
    } elseif($day == "thursday") {
        echo "1 days untill it's friday";
    } elseif($day == "friday") {
        echo "Today friday";
    }
}
?>
