note 98139 added to function.serialize

serialize can be a handy tool for protecting against page expirations if you are using POST's. 

In my code I call the following function whenever I detect that the page has expired.

<?php
function savePost() {
    // Save this in the login form
    if (isset($_POST['savePost'])) {
        echo "<input type='hidden' name='savePost' value=\"{$_POST[savePost]}\">";
    } else {
        $savePost = htmlspecialchars(serialize($_POST));
        echo "<input type='hidden' name='savePost' value=\"$savePost\">";
    }
}
?>

and when I load each page I call the function:

<?php
function restorePost() {
    if (isset($_POST[savePost])) {
        $_POST = unserialize(stripslashes(htmlspecialchars_decode($_POST[savePost])));
    }
}
?>

That way if a user takes a long time doing something, they can re-authenticate and have their work restored.
