He has been actively involved since May 2001 as a developer and project administrator. phpMyAdmin is now a part of his life. He has worked since 1980 at Collège de Sherbrooke, Québec, Canada, as an application programmer and network manager. He has also been teaching networking, security, Linux servers, and PHP/MySQL application development. In one of his classes, he was pleased to meet a phpMyAdmin user from Argentina. I am truly grateful to Louay Fatoohi, my editor, who approached me for this book project, and accompanied me during the production; his sound comments were greatly appreciated. My thanks also go to Garvin Hicking, a member of the phpMyAdmin's development team and the reviewer for this book. Garvin's sharp eye helped in making this book clearer and more complete. Finally, there would be no book about phpMyAdmin without phpMyAdmin (the software). I wish to thank all contributors to the source code and documentation; the time they gave to the software project still inspires me and continues to push me forward. To Carole, André, Corinne, Annie, and Guillaume, with all my love. About the Reviewers Garvin Hicking is a German web developer working for Faktor E GmbH. He creates web applications using PHP and MySQL, and in his free time enjoys working on open-source projects like phpMyAdmin or Serendipity. When he's away from the computer, he likes going to the movies with his girlfriend and friends, blogging, and taking pictures. What he enjoys most about his work in Open Source is making people's everyday life easier, by giving them free, but powerful, tools to play with. Receiving feedback from satisfied users is one of the fundamental give and get principles he likes to live by. Alexander Marcus Turek was born on June 2nd, 1984 in Düsseldorf, the capital of the German province Northrhine-Westphalia. Currently, he's studying Information Engineering and Management at the University of Karlsruhe, but his origin is Mülheim an der Ruhr, the home of his family. He first got in touch with the Web in 1998, when he won a 28.8k modem at the CeBit Home in Hannover, Germany. A few months later, he learned HTML and started his first Web project, a German game patch archive called Rabus' Update Site, which he renamed to bugfixes.info, when the .info domains became available. In the meantime, he switched from static HTML to PHP in order to be able to manage the growing archive more efficiently. He kept on learning PHP when trying to extend the portal. Because the flatfile-based database system became too slow when searching the still growing archive, he also switched to MySQL in 2001. This is when he got in touch with phpMyAdmin and the project. He started with revising its language files because they were a bit outdated and inconsistent. He had fun doing so, and continued with grabbing some bug reports and submitting patches for them. Loïc Chapeaux, one of the two co-maintainers at that time, added him to the developers list and gave him a CVS account in March 2002, so he could merge his patches by himself. Since then, he has mainly worked on the compatibility with MySQL 4.0, reworked the server administration area, developed a simple abstraction layer in order to support MySQLi, and continued with compatibility fixing—this time for MySQL 4.1 and 5.0. Unfortunately, his studies and phpMyAdmin became too time consuming, and he had to stop working on bugfixes.info in 2003.
