⚠️ Experimental Status: These projects are currently in experimental phase. While they work correctly and pass all tests, please use with caution in production environments. We recommend thorough testing in your specific use case before deployment.

A high-performance PHP extension for CSV file handling, providing significant improvements in speed and memory efficiency compared to PHP's native CSV functions.

• 3.6x to 4.8x faster than native PHP CSV functions for read operations (validated by benchmarks)
• 1.6x to 2.9x faster for combined read/write operations
• Read Performance: Up to 568K records/sec vs 156K records/sec (SplFileObject)
• Write Performance: Up to 339K records/sec vs 136K records/sec (SplFileObject)
• Built on top of FastCSV-C library
• Supports PHP 8.2, 8.3, and 8.4
• Cross-platform (Linux, macOS, Windows)
• MIT License

A standalone, high-performance C library for CSV processing with minimal memory footprint.

• Zero dependencies
• Thread-safe design
• Cross-platform compatibility
• Powers the FastCSV PHP extension
• MIT License

A modern PHP library that provides a unified interface for CSV processing, automatically using FastCSV when available.

• Intelligent Performance: Automatically uses FastCSV (3.6x-4.8x faster) when available
• Reliable Fallback: Falls back to optimized SplFileObject implementation
• Memory Efficient: Constant memory usage with streaming for datasets of any size
• Automatic implementation selection
• Consistent API across implementations
• Type-safe with full PHP 8.2+ features
• MIT License

A comprehensive benchmarking suite for comparing FastCSV extension performance against native SplFileObject implementation.

• Docker-based environment for consistent testing
• Multiple data sizes (1K, 100K, 1M records)
• Automated performance measurement and reporting
• Validates the 3.6x-4.8x performance improvement claims
• MIT License
