About the Solar Project
Solar is a web application framework for PHP 5. It is the brainchild of Paul M. Jones who winkingly calls himself the "Benevolent Dictator" of the Solar system. Other developers are working on additional components for the standard project distribution package, all under the New BSD license.
Why Use Solar?
Thorough integration of enterprise development patterns, such as:
Full name-spacing: Solar classes have their own PHP 5.2 name-space, and vendors developing to Solar standards also use their own name-space. This makes it easy to mix and match components from other libraries and frameworks.
Inheritable configuration by class: Set a value in the config file for one class, and all its children inherit those values by default.
Inheritable localization by class: Set the locale strings for a class, and all its children inherit those strings.
Easy-to use defense-in-depth against SQL injection, cross-site scripting, cross-site request forgery, and other common exploits.
Robust and powerful model system that lets you create forms automatically from record objects.
Sane and extensible data filtering to validate and sanitize user input.
Authentication adapters for LDAP, TypeKey, database, htpasswd, and other sources.
Cache adapters for memcache, APC, XCache, and other systems.
