LionWiki

LionWiki is a minimalist Wiki engine programmed in PHP. It is extensible, templatable, file based (it doesn't need database like MySQL) and requires just one file to properly function. It is suitable for small sites, personal notebooks or journals. LionWiki is fork from french-only WiKiss.

Features
Feature set is purposely limited to maintain the biggest advantages over other Wiki engines - small size and simplicity to install and use.

LionWiki provides essential Wiki functionality like Wiki syntax, revision history, last changes, renaming pages, password protection (both read and write) and other functions.

Further functionality is provided by plugins, e.g. powerful table syntax, RSS feed with page changes or spam filtering Captcha.
