PHP包括代码显示一件事，但浏览器显示另一件事

Question

我在一个看起来像这样的网页上有一系列的php ...

<?php include 'folder1/file.php'; ?>
<?php include 'folder2/file.php'; ?>
<?php include 'folder3/file.php'; ?>

它们在我的代码编辑器中看起来像上面那样，但是当我上传到我的服务器时，当我查看源代码时，它会像这样查看...

<?php include 'folder1/file.php'; ?>
<?php include 'folder3/file.php'; ?>
<?php include 'folder3/file.php'; ?>

所以我想也许文件没有上传....所以我把代码更改为此并上传了页面....

<?php include 'folder1/file.php'; ?>
<?php include 'folder3/file.php'; ?>

当在任何浏览器中查看它时，它按预期查看，只显示两个包含。告诉我网页正在上传到服务器。我已经清空了缓存，刷新了页面而没有任何内容。那么当我将代码更改回此并上传....

<?php include 'folder1/file.php'; ?>
<?php include 'folder2/file.php'; ?>
<?php include 'folder3/file.php'; ?>

它仍然在实况页面中显示了这一点

<?php include 'folder1/file.php'; ?>
<?php include 'folder3/file.php'; ?>
<?php include 'folder3/file.php'; ?>

我在服务器上安装了PHP，所有其他PHP代码/包都正常工作。以下PHP代码可以正确运行。

<?php phpinfo(); ?>

这是folder2 / file.php的代码
