PHP Chess
PHP Chess is a library implemented in PHP that allows to create chess apps out-of-the-box.
One key feature is that it has been designed with OOP principles in mind and is thoroughly tested with plenty of unit tests. The unit tests are the best documentation. They contain hundreds of real examples on how to use the PHP Chess library.
Almost every class in the src folder represents a concept that is tested accordingly in the tests/unit folder, in other words, the structure of the tests/unit folder is mirroring the structure of the src folder. For further details on how to use a particular class, please feel free to browse the codebase and check out the corresponding tests.
The PHP Chess docs are more of a tutorial rather than an API description.

Object-Oriented
The chess board representation is an object of type SplObjectStorage as opposed to a bitboard.
Thoroughly Tested
PHP Chess has been developed with a test-driven development (TDD) approach. The tests/unit folder contains plenty of real examples.
Lightweight
PHP dependencies required:
- Rubix ML for machine learning.
- Imagine for image processing.
