我正在设计这个网站，我需要它是 .php 以与数据库通信并启动一些倒计时时钟（尚未启动）。该页面最初是 .html 并且一切都很完美，但由于我出于某种原因将其更改为 .php，因此页脚不断重复。代码在我的编辑器上会很好，我将加载页面，在编辑器上重新加载文件，代码会以某种方式单独出现在那里！现在没有任何 PHP 代码，我只是更改了文件的扩展名。如果您访问相同的 URL 但 .html 版本，您会发现一切正常。这可能是什么原因造成的？
在此先感谢您的帮助！

之后真的很尴尬地重复了一遍。它可能是 FTP 服务器，我为此使用Koding（不要问），它通过 FTP 连接到我的服务器。我也尝试过使用 FileZilla（在重新上传之前没有删除文件），但这并没有做任何事情。
