Experimental PHP client for new Responses API

Hey everyone,

Thanks for the great work and exciting announcement yesterday regarding the Responses API! :tada:

To explore the new OpenAI Responses API with PHP, I built an experimental PHP client and released it as open source on GitHub. If youโ€™re a PHP developer and want to try out the new endpoints, feel free to check it out! :slight_smile:

Looking forward to this year of agents! :rocket:

Best,
