Each application has 2 bars at the top: status bar and title bar. Sometimes it's useful to remove/hide them (especially in gaming apps).

In this tutorial I will explain how to create a progress bar for PHP file uploads.

This allows you to store data across sessions and includes built-in functionality for storing/returning file upload stats.
