Comparator
This library is a data assertion tool and equality logic framework for PHP. It provides utilities to verify that two values, nested objects, or complex data types match based on their internal contents.
The project distinguishes itself through the use of custom matching rules and configurable precision. It allows for the comparison of floating point numbers and dates using a defined margin of error to account for numeric precision loss.
The framework covers deep value equality verification across scalars, arrays, and nested objects. It implements strict type enforcement to prevent implicit conversions and uses recursive traversal to analyze internal data structures for integrity validation.
