Automap is a fast map-based PHP autoloader. It resolves symbols using map files. These files are created offline by a program (included) which scans your script files and extracts their symbols. At runtime, map files are loaded by the main script and then used to resolve undefined symbols and load the corresponding PHP script files. An optional PECL extension is available to make it faster still.
SCMS is an MVC based secure content management system. It is designed from the ground up to withstand common Web application vulnerabilities such as SQL injection, XSS, CSRF, session fixation/hijacking, and many others. It is designed for PHP 5.0-5.2.x and MySQL 4.1+, and it can optionally support PostgreSQL as a database backend.
