Why same content with different file type result in different output?
分享 Because you have your webserver configured to pass *.php files through the PHP interpreter which executes the PHP contained within the PHP files.
HTML files aren't configured that way on your webserver (though you can configure it to do so). As it is, the server believes it is just a plain HTML document and is returning it verbatim, and the browser is interpreting your PHP open/close tags as HTML tags that it just doesn't recognize and doesn't know what to do with (try to view the source and see if your PHP code is showing up in the source).
