the complete, portable server
XAMPP is an integrated server package of Apache, mySQL, PHP and Perl (the AMPP in XAMPP) that all run from a removable drive. Everything is pre-configured and ready to go just by unzipping or installing it.
Menu Integration: XAMPP isn't in PortableApps.com Format, but it easily integrates with the PortableApps.com Suite by using the XAMPP Launcher 1.5 and installing XAMPP in the root directory of your portable device (as recommended). You can open the self-extracting archive with 7-Zip Portable or download the larger ZIP archive.
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.
Add-Ons: You can also add in Perl or Tomcat with the XAMPP Add-Ons.
