Gregory Beaver has been one of the most active contributors to open-source PHP development since 2001. As the primary developer of important infrastructure software such as phpDocumentor, the PEAR installer, PHP_Archive, PHP_LexerGenerator, and PHP_ParserGenerator as well as co-lead of the Phar PHP extension, Gregory has helped to ease the development needs of PHP developers around the world. After he transformed phpDocumentor from a small project into the most advanced auto-documentation tools for PHP, phpDocumentor was voted second best PHP tool in Germany-based PHP Magazin's 2003 Reader's Choice awards list for best PHP application, and voted third best PEAR package (http://tinyurl.com/bn7pb). Currently, he is working to refactor the PEAR installer for PHP 6, as well as helping to lead the PEAR community forward. Gregory blogs about his programming escapades and other news on his blog, Lot 49 (http://greg.chiaraquartet.net). Gregory also leads a mysterious double life as the cellist of the internationally renowned Chiara String Quartet (http://www.chiaraquartet.net) with whom he tours the world. He lives in Lincoln, Nebraska where he is a full-time lecturer/artist-in-residence at the University of Nebraska-Lincoln Hixson-Lied College of Fine Arts.
