I was hoping that some of you would be able to give me some advice.
I have started creating a web application that makes heavy use of URL GET
variables in order to solve a problem that I have had with POST in the
past – namely, having to refresh the document and repost the variables when
you use the browser’s back button.
So I enthusiastically have embraced GET variables, but am now having a
struggle editing the URL variable string.
So this is my question: is using URL GET variables that best way to avoid
that browser back button effect?
I have thought about using session variable extensively, but that I am going
to have to be unsetting them all over the place.
So – anyone have any advice?
Thanks in advance!

It can be a good way, but I believe the spec for GET based parameters
only guarantee processing of 1024 characters (this may be the wrong
number but there is a limit on the guarantee).
If you are worried about unsetting them all, maybe it would help to use
a two level array to hold your form data. Perhaps the following:
$_SESSION[‘formName’][’email’] = $_POST[[’email’];
Then when you want to clear the form you can do a simple:
unset( $_SESSION[‘formName’] );
