Better Reflection

Better Reflection is a reflection API that aims to improve and provide more features than PHP's built-in reflection API.

Why is it better?

• You can reflect on classes that are not already loaded, without loading them
• Ability to reflect on classes directly from a string of PHP code
• Reflecting directly on closures
• Ability to extract AST from methods and functions
• Ability to return AST representation of a class or function
• Fetch return type declaration and parameter type declarations in PHP 7 code
• Moar stuff coming soon!

Typically you would use Better Reflection for static analysis tooling. It can serve as a baseline to access type information (e.g. doc blocks, type declarations), method/function body AST fetching etc. for static analysis.

Better Reflection is NOT suited to runtime usage, since performance is much worse than PHP built-in reflection. If you do not want to do anything that native PHP reflection can't do, then just use native PHP reflection! The "Better" in Better Reflection refers to feature, not speed!

Be sure to read more in the feature documentation.
