When learning HTML, click "Run Example" and click "Submit", but the white box on the right has no response.

Question

I had to go to php.cn.htm on my computer desktop and copy the code to refresh it every time. I tried using IE and Chrome browsers, but nothing happened when I clicked "Run Instance". Are web browsers upgraded and no longer support old web pages? Or is there something wrong with the web pages?
