PHP GPT-4 Function Calling Example

This is an example code for using the OpenAI GPT-4 API's function calling capability. There is a chatbot.php in the repostiory, which is a command line chatbot that you can use to interact with ChatGPT.

There is also a work-in-progress ChatGPT PHP library in the library/ChatGPT.php file that can work with function calling.

The chatbot has been programmed, using GPT-4 function calling, to answer to queries about the weather with "It's nice and sunny". It also has a shopping cart, into which you can add products and list the contents of.

Usage

Export your OpenAI API key:

$ export OPENAI_API_KEY=YOUR_API_KEY

Run the chatbot:

$ php chatbot.php
