Dunno，作为PHP的相对新手，但是快速谷歌提出了这个

这有帮助吗？

I have the following for a test of the submit button being pressed:

if (isset($_POST[''theSubmitButton''])) {

This works fine and I have been doing this for a long time. Here is the
question:

If I do a submit and have it come back to the same page, all is fine. If I
now click the browser refresh button, I get another submittal. How do I
"unset" the status so that it doesn''t think I clicked the submit button when
I click the refresh button?

Dunno, being a relative newbie to PHP, but a quick Google brings up this

Does that help?
