The BadBlue Personal Edition server (a free download at http://badblue.com/down.htm) has been called "the fastest and easiest way to get PHP up and running on Windows systems". BadBlue can be downloaded and running PHP in literally a matter of minutes. PHP and similar CGI configuration is accomplished with a few quick, simple steps ( http://badblue.com/helpphps.htm ).
The Enterprise Edition server includes the complete BadBlue Encoding System (http://badblue.com/helpphpe.htm) which allows users to create redistributable (and even expiring) versions of their applications.
BadBlue also supports integrated scheduling, live peer-to-peer sharing of Access, Excel and Word data, built-in Napster-style file searches and downloads and other features that make it a unique blend of web serving and peer-to-peer capabilities.
Rated five stars by Tucows, four out of four Meerkats by O'Reilly and featured on TechTV, BadBlue is an easy way to get started with PHP or simply to share files for home or business using a web browser as the means for searching and sharing.
