在PHP中创建的文本文件中包含页面代码

我试图从表中获取数据，使用PHP将它们写入文件并强制下载，但每当我下载文件时，它总是有页面代码加上我想要的文件。

你能看到我的PHP代码有什么问题

<?php


if (empty($_POST['file'])) {

    echo "<div>";
    echo "<h1 align='center'>ERROR:</h1>";
    echo "<p align='center'>Something is missing, please go back and check your error!</p>";
    echo "<div class='error' width='50%' height='50%' align='center'><img src='./images/error.png'/></div>";
    echo "</div>";  
}

您在输出文件之前专门输出HTML：

echo "<h1 align='center'> SUCCESS :</h1>";
echo "<p align='center'> The transcription has been successfully made, you can download you file by clicking on the";                  
echo "button below.</p>";
echo "<p align='center'> Right-click on the button below, click on 'Save link as' </p>";
echo "<center>";
echo "<div class='success' width='50%' height='40%' align='center'><img src='./images/success.png'/></div>";

如果您不希望将其包含在下载中，请将其删除。

您无法同时下载文件并在页面上显示信息。只需点击一下即可在浏览器中下载一个“内容”： 网页< em>或保存到磁盘的文件。

如果您想要显示“成功”并同时下载文件，一种常见的技巧是在页面上输出“成功”，然后将访问者重定向到下载URL，以便立即开始下载。 （通常这种页面附带“你的下载应该立即开始......”的消息，大家都不喜欢。）
