The first version, by Steve Wainstead, was in December 1999 and was the first Wiki written in PHP to be publicly released. The first version ran under PHP 3.x and ran on DBM files only. It was a feature-for-feature reimplementation of the original WikiWikiWeb at c2.com.
In early 2000 Arno Hollosi contributed a second database library to run PhpWiki on MySQL. From then on the features and contributions started to grow, including a templating system, color diffs, rewrites of the rendering engine and much more. Arno was interested in running a wiki for the game Go.
Jeff Dairiki was the next major contributor, and soon headed the project for the next few years, then Reini Urban up to 1.4, and then Marc-Etienne Vargenau since 1.5.
Supports Wikicreole 1.0 including additions and MediaWiki markup syntax since Version 1.4.0. With Version 1.5.0 PHP 4 was deprecated.
