After I've read the $_POST variables I'd like to set e.g.
$_POST['myinput'] = "already used"

Therefore I could figure out if this page has been reloaded (F5) or called
again from the page before.
If this page is reloaded (F5) $_POST['myinput'] would be "already used" and
if it's called from the page before $_POST['myinput'] would be something
else.

However, if I reload or press the back button on the browser
$_POST['myinput'] is not set to "already used" but it's set to the value it
was before.

How can I delete or reset the $_POST variables so they are changed also if
you reload or press the back button on the browser?
