if your server isn't set up to process .html for the php tag, you're fine to do exactly what you've done.如果您的服务器没有设置为处理 php 标记的 .html，那么您可以完全按照您所做的去做。
You can also use this: <?php which would render as <?php but not be seen by PHP.你也可以使用这个： <?php它将呈现为<?php但不被 PHP 看到。

One option you can use is PHP's highlight_file() function:您可以使用的一种选择是 PHP 的highlight_file()函数：
<?php
highlight_file("your_file.php");
?>
You can also use .html file extensions highlight_file("your_file.html") .您还可以使用.html文件扩展名highlight_file("your_file.html") 。
Even a .txt file extension highlight_file("your_file.txt") .即使是.txt文件扩展名highlight_file("your_file.txt") 。
