<?php
// This script has two functions, either ask for data, or display data.
// Check if we have both variables we care about:
if (isset($_REQUEST['firstname']) && isset($_REQUEST['zipcode'])) {
    // Update or create the cookies, all set to expire in 1 hour:
    setcookie('firstname', $_REQUEST['firstname'], time()+3600);
    setcookie('zipcode', $_REQUEST['zipcode'], time()+3600);
    
    // Now, also, just print the standard output:
    echo "
<p>Welcome back {$_REQUEST['firstname']}!  Perhaps you would like to see
 things happening near your home zipcode ({$_REQUEST['zipcode']}) ?</p>
";
} else {
    // We have nothing, so make a form so they can provide data.
    echo "
<form action=\"{$_SERVER['PHP_SELF']}\" method=\"POST\">
<p>What is your first name? <input type=\"text\" name=\"firstname\" /></p>
<p>What is your zipcode? <input type=\"text\" name=\"zipcode\" /></p>
<p><input type=\"submit\" /></p>
</form>
