Description:

Zend_Reflection is a drop-in extension to PHP's own Reflection API,
providing several additional features:
- Ability to retrieve return values types.
- Ability to retrieve method and function parameter types.
- Ability to retrieve class property types.
- DocBlocks gain a Reflection class, allowing introspection of
docblocks. This provides the ability to determine what annotation tags
have been defined as well as to retrieve their values, and the ability
to retrieve the short and long descriptions.
- Files gain a Reflection class, allowing introspection of PHP files.
This provides the ability to determine what functions and classes are
defined in a given file, as well as to instrospect them.
- Ability to override any Reflection class with your own variant, for
the entire reflection tree you create.

In general, Zend_Reflection works just like the standard Reflection
API, but provides a few additional methods for retrieving artifacts
not defined in the Reflection API.
