This is a PHP library for Chinese text processing, providing functions for pinyin conversion (with tone marks, tone numbers, and first letters), pinyin segmentation, simplified/traditional Chinese conversion, number-to-Chinese-spoken conversion, and number-to-Chinese-financial (money) conversion. The library supports multiple data backends: Memory (loads all data from SQLite into memory for performance), SQLite (queries on demand with low memory), JSON (compatibility mode with reduced data), FFI (uses a C++ shared library via PHP FFI for maximum performance), and SwooleFFI (non-blocking FFI for Swoole coroutines). The architecture follows a strategy pattern with a facade (`Chinese` class) that delegates to mode-specific drivers. The code is well-structured, includes comprehensive tests for all modes, and handles edge cases such as multiple character readings (多音字) and zero values. The library is self-contained with bundled data files and precompiled FFI binaries for multiple platforms.
