Source Code for Canon Lens Specification Search

This is a simple application that I hacked together on the way home from work. (MARTA was particularly slow that day.) The application queries a small MySQL database to select Canon lenses based on requirements that the user provides via a CGI form.

Here is a description of the source files:
canon.php   The actual PHP application
db_canon.sql   The Canon lens database schema and contents.
db_session.php   Session handling code reused from the PHP Cookbook.
db_session.sql   The database schema required by the session handling code.
db_canon.php   Code to connect to the database server and setup sessions.

Drop me a note if you have any suggestions, comments, or questions.
