CLI ChatGPT Client in PHP

For my personal use, I created a CLI ChatGPT client a few months ago. It has been very useful for me to have it available in the CLI quickly whenever I needed it (caveat, you need an API key!).

Unfortunately, for larger responses it can feel very slow, whereas the web version feels quite fast. But this is perceived speed because it shows you each word as it arrives and not just the whole response when finished (after all it is a completion AI that generates the response word by word).

So now, I have added streaming support to it. It now feels almost too fast :) The CLI has a few nice things such as readline support (i.e. you can go back to old queries with the up key) and it keeps all of your conversation in a text file. All of this in only 100 lines of PHP.
