Well, I've tried everything that has been suggested so far - thanks for
everyone's input.

However, let me restate the problems differently as I believe it wasn't
correct to begin with.

I have a file: index.php

index.php contains a form, which when submitted for processing, calls
itself using <form method="POST" action="{$_SERVER['PHP_SELF']}">

When the form is submitted and index.php is reevaluated, I have the
following IF statement: (FYI: 'submit' is the name of the submit button.)
------------
IF ( !isset($_POST['submit']) ) {
// The form has NOT been SUBMITTED - display the form

echo <<<htmloutput
<form method="POST" action="{$_SERVER['PHP_SELF']}">
...
</form>
htmloutput;

} ELSE {
// The form was SUBMITTED - process the form

process the form data, etc. and print in PLACE of the form the
following:

echo "Information submitted... Thank you.";
}
-------------

I understand I can redirect to a (different) summary page, but all I
want to do is replace the form with the summary message. The problem
comes into being when, after the summary message is displayed, the user
goes to refresh the browser. The browser is still caching the form data
for resubmission. I've tried things like: unset($_POST) or
unset($_POST['submit']) (and all the other form fields) but that has no
affect.

Any other suggestions?

Thanks in advance.
