So the logic of the php script, as I understand it is

script is called without any sort of argument in the URL and generates a
page.

The value for the variable is obtained through a $SESSION variable or
some default. A form with a button is displayed, possibly with a number
showing the value of the autoincrement variable.

Click on the button, which must be part of a form. The form submits the
page using the script $_SERVER['PHP_SELF'], passing the autoincremented
variable as a $_GET variable.

The resulting page displays, determines that $_GET[variable] is set, and
uses that value rather than the session

I don't see how reloading the page comes into this. When you click the
<button>, that should submit the form and redraw the page. a <button>
tag That's usually used for "hands off" automatic reloading.

If this isn't part of the logic you're trying to accomplish, correct me
where I don't have it right.
