如何用$ message替换整个表单？

I am new in php, so I need your help. At first I created two .php files. The first included a form and the second included the message.

I wish to replace the form to a message in the same page after submit. how I do that?

<?php
  $message="";
  if (isset($_POST["submitButton"])) {
    $name= $_POST["name"];
    $age= $_POST["age"];
    $username= $_POST["username"];
    $message= "your name is ". $name. ",you are ".$age
    ." and your reddit's username is ".$username;
  }
 ?>

<html>
  <head>
    <meta charset="utf-8">
    <title>new file</title>
  </head>
  <body>
    <?php echo $message; ?>
    <form  action="" method="post">
    <table >
      <tr>
        <th>name:</th>
        <td>
          <input type="text" name="name" >
        </td>
      </tr>
      <tr>
        <th>age:</th>
        <td>
          <input type="text" name="age" >
        </td>
      </tr>
      <tr>
        <th>username:</th>
        <td>
          <input type="text" name="username">
        </td>
      </tr>
    </table>
    <input type="submit"  value="click here for save" name="submitButton">
  </form>
  </body>
</html>

    Put the form in a conditional.

    <?php
  $message= isset($_POST["submitButton"]) ? "your name is ". $_POST["name"]. ",you are ".$_POST["age"]
    ." and your reddit's username is ".$_POST["username"] : "";
 ?>

<html>
  <head>
    <meta charset="utf-8">
    <title>new file</title>
  </head>
  <body>
    <?php if (!empty($message)) {
         echo $message; 
     } else { ?>
    <form  action="" method="post">
    <table >
      <tr>
        <th>name:</th>
        <td>
          <input type="text" name="name" >
        </td>
      </tr>
      <tr>
        <th>age:</th>
        <td>
          <input type="text" name="age" >
        </td>
      </tr>
      <tr>
        <th>username:</th>
        <td>
          <input type="text" name="username">
        </td>
      </tr>
    </table>
    <input type="submit"  value="click here for save" name="submitButton">
  </form>
    <?php } ?>
  </body>
</html>
