    PLEASE NOTE:

    This is code to generate a selection entry form for a future date, not a
    function to validate dates.

    futureDateFormEntry():
    Quick, easy addition of future date fields to HTML code using PHP.
    Handy for requesting expiration dates, dates for delivery, dates for
    appointments, or any web application that requires obtaining a future
    date from the user.

    validFutureDate():
    Checks that entry is indeed a valid future date.


    Code introduction comment contains a fully functional example for illustrative/testing purposes.

    * futureDateFormEntry():
    * Quick, easy addition of future date fields to HTML code using PHP.
    * Handy for requesting expiration dates, dates for delivery, dates for
    * appointments, or any web application that requires obtaining a future
    * date from the user.
    *
    * Function requires only 3 arguments if you are happy with the defaults:
    * The 3 required arguments are a mechanism for preserving the user's valid
    * input from previous edits of the form (re-entrant form code). They may
    * be NULL, in which case the default selection parameters apply.
    *
    * Example:

    <?php
    include('FutureDateFormEntry.php');
    $userName=$_REQUEST[yourName];
    $enteredDay=$_REQUEST[expiryDay];
    $enteredMonth=$_REQUEST[expiryMonth];
    $enteredYear=$_REQUEST[expiryYear];
    $goodEntry=true;
    $entryMade=($enteredDay && $enteredMonth && $enteredYear);
    if($entryMade)
    $goodEntry=validFutureDate($enteredDay,$enteredMonth,$enteredYear);
    ?>
    <html>
    <head>
    <title>Untitled</title>
