filetype只是识别文件的一种方式，你不能总是信任它们。
根据你的web服务器配置，你会看到不同的结果。
.html通常只用于没有服务器端代码的HTML。
.php用于服务器端php代码和html。
它们可以用于任何事情，它只取决于设置。
I am having a .php file with the following code. While I am changing the extension of the file as .html then also it is behaving in the same way. Can anyone explain the following:
- Why the file is behaving in the same manner with both the extensions?
- What is the difference between the
.phpand.htmlfile extensions?
.php file
<html>
<head>
<!-- some html code -->
</head>
<body>
<?php echo "Hello!" ?>
</body>
</html>
The filetype is just a way to identify the file, you can't always trust them.
Depending on your web server configuration, you will see different results.
.html is generally use just for html with no serverside code.
.php is used for serverside php code and html if required.
They can be used for anything, it just depends on the setup.
