PHP文件在服务器上变得完全为空

Question

因此，出于某些原因，我可以使用GoDaddy将这个单独的PHP脚本上传到我们的服务器上，它将正常工作一两天，然后停止工作。我已经知道，如果我只是简单地重新上传文件，它就会重新开始工作。在这种情况发生了几次之后，我联系了GoDaddy支持。在与GoDaddy支持人员交谈后，当它不工作时，我们意识到该文件是完全空的。在我们的服务器上只有一个0字节的PHP文件。GoDaddy支持人员说，这不可能是他们的错，一定是我的脚本中有什么问题，但我不知道是什么原因可能会删除文件中的所有代码。这是更改了一些安全数据的完整文件，也许您可以找到它。

为了好玩，这里有一个PHP文件，它会在两天后删除它自己的内容。

<?php
if (time() - filemtime(__FILE__) > 172800) {
    $handle = fopen(__FILE__, 'r+');
    ftruncate($handle, 0);
    fclose($handle);
}

我在你的文件中看不到任何可以实现这一点的东西，即使是间接的。
