The O'Reilly School of Technology now offers a series of PHP certification classes developers can attend to learn more about PHP and SQL on a variety of projects.

The PHP/SQL Programming Certificate Series is comprised of four courses covering beginning to advanced PHP programming, beginning to advanced database programming using the SQL language, database theory, and integrated Web 2.0 programming using PHP and SQL on the Unix/Linux mySQL platform.

They currently offer three courses:

• Introduction to PHP
• PHP/SQL 1: Introduction to Database Programming
• PHP/SQL 2: Relational Theory and Logical Design

Another class will be released in December 2008 - PHP/SQL 3: Seamless Web 2.0 Integration . The classes come it at a bit under $400 USD and include access to an online sandbox for testing (complete with web server, unix-shell and database installations). Completion of all four courses earns the student a certification from the University of Illinois's Professional Development department.
