    ?>
    <form action='index.php' method='post'>
    What time is it? <input type='text' name='time' /> <br />
    <input type='submit' value='Submit'>
    </form>

Answer 1

Variables in PHP are case-sensitive. In your example, changing $_post to $_POST seems to have the desired outcome, since the superglobal $_POST 是脚本执行时 POST 数据存储的位置。

您还需要确保脚本的名称实际上是 index.php，因为这是表单将 POST 数据发送到的地方。
