Features

XAMPP ScreenshotXAMPP is a complete web, database and FTP server package for Windows that's ready to go in minutes and completely portable. The full XAMPP package includes:

* Apache
* MySQL
* PHP + PEAR
* MiniPerl
* OpenSSL
* phpMyAdmin
* XAMPP Control Panel
* Webalizer
* Mercury Mail Transport System
* FileZilla FTP Server
* SQLite
* ADODB
* Zend Optimizer
* XAMPP Security

XAMPP Lite leaves off the additional packages and sticks to Apache, mySQL, phpMyAdmin, SQLite and related packages resulting in an installation that's significantly smaller. There are no upgrade packages for XAMPP Lite like there are for XAMPP, though.
