php - Browser displaying PHP code

Question

I am running XAMPP in order to use PHP on my local computer. I put all of my scripts inside of the htdocs folder (the default location). Everything used to work great until recently. For example, if I click on an HTML file in htdocs, the file opens up in a browser(like it should). But, if I click submit on a form with an action set to "some-script.php" It goes to the php page and displays the php code. Now, if I type into my browser "localhost/some-html.html" then it works? Why is that? What could I be doing wrong??

Answer 1

当您通过在地址栏中键入“localhost/some-html.html”来访问它时，您使用 XAMPP 的服务器和 PHP 引擎来访问该页面，当您只需双击文件夹中的文件时，您只是使用默认打开文件程序（恰好是您的浏览器）

Answer 2

定义一个基本 url 变量，如 $baseurl = "http://localhost/foldername/"，并在您的操作中使用此变量，如 action = "example.php"。
