怎么使用PHP实现表单数据提交并跳转页面

<h4>表单提交示例</h4>
<form method="POST" action="submit.php">
  <p>
    <label for="name">姓名:</label>
    <input type="text" name="name" id="name" required>
  </p>
  <p>
    <label for="email">邮箱:</label>
    <input type="email" name="email" id="email" required>
  </p>
  <p>
    <label for="message">留言:</label>
    <textarea name="message" id="message" required></textarea>
  </p>
  <p>
    <button type="submit">提交</button>
  </p>
</form>

<?php
// 获取表单数据
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

// 对表单数据进行处理：例如，可以将数据保存到数据库中

// 页面跳转
header('Location: success.php');
exit;

<?php
// 获取表单数据
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
?>

<h4>提交成功</h4>
<p>您的姓名：<?php echo $name; ?></p>
<p>您的邮箱：<?php echo $email; ?></p>
<p>留言内容：<?php echo $message; ?></p>
