Warnings

deprecated This project is experimental and not recommended for production use. Use at your own risk. ↓

fix Consider using alternative transpilers or rewriting code manually in PHP.

gotcha Core JavaScript APIs (e.g., Array functions, JSON) are only partially converted and may produce incorrect PHP code. ↓

fix Check the converted PHP output carefully and manually fix any missing or incorrect implementations.

breaking Date object support is explicitly missing ("Date (missing)" in README). ↓

fix Do not use Date in JavaScript code intended for transpilation, or manually implement date handling in PHP.
