PHP articles

Hi, Several people have responded to my request for a php howto author, so I am posting more information about what I am wanting. The PHP articles will be published in the PHP Dev Center on The O'Reilly Network. http://www.oreillynet.com/php I have a few ideas for the DevCenter, but I am open for other ideas. Here is what I was thinking: A Basic Intro Column written either weekly or bi-weekly, taking people through the basics of getting a web page written in PHP. Assumes that php is already installed and someone else is maintaining it. An advanced php Column, gets into the deeper programming techniques and tricks. Would contain alot about how to connect to databases and utilize them in programs. Written weekly, bi-weekly, or monthly. A developer/sysadmin column. How to setup php, cool things you can do with php on the server side. Commonly asked server setup questions, keeping current with development releases and features. Developer stuff. Programming modules for php, coding php, etc... Can be written bi-weekly or monthly. I am also looking for feature articles that would only be published separately or in a small series of 3 or less. These could cover anything related to php. The average payment for articles is about $350 per article, with articles ranging from 800 words to 1500 words.
