单击按钮时显示div（PHP）

Question

I am a first poster here so please excuse my noob-like behavior.

I have a button on my website that when pressed should disappear, and a form should be echoed out in its place without a page refresh.

I have easily achieved this with JavaScript / AJAX, but if JavaScript is disabled, I still want the button to do it's task.

My question is: Can I do this only using PHP, WITHOUT a page refresh?

Not in a way I think you'd want to do it, but you could use an iframe that contains the button. The button would be a link or form submit and the navigation would happen inside the iframe to your form. This way, only the iframe is refreshed, but the full page remains unchanged.
