halaxa/json-machine ? reverse-engineered prompt

Build me a small PHP library for reading huge JSON files without loading everything into memory.

I want to be able to point it at a file or any stream, then loop through the data with a normal foreach and get one item at a time. It should work for both JSON objects and arrays, and let me read just a part of the document if I give it a JSON Pointer path, like a nested section or even a single value. It should also handle JSON coming from an API response stream, not just local files.

Please make it easy to use, memory efficient, and fast, with a simple default setup. If it helps, support returning either objects or arrays, and include a way to handle bad JSON items cleanly. Add a few example scripts and tests so I can see how to use it right away. If you need to look up current PHP docs or best practices, feel free to do that.
