Creating PHP GPT-4 Function Calling Chatbot From Scratch

In today's video I implement a simple terminal based chatbot using the GPT-4 function calling API with PHP. In the next video I will create a library with this so that it will be easy to integrate to your existing project, so make sure to subscribe!

What an incredible video! Commenting from the future where we now have GPT-4 turbo. I was basically confused on that part of looping conversations. My database structure just seem coded for the previous version. Now I have to re-design the flow of conversation history and the function calling. Would be glad if we could see another update php version with the GPT4V version. Not sure it supports function calling too.
Thanks for the cool video

great!

Interesting video, thanks a lot. I'm also using visual studio code but I didn't know that I can select several characters in several lines of code and replace all marked selections at once. Good to know that this is possible. Do I need a plugin for this or is it a standard feature?

[@unconv]

It's a standard feature. If you select a word and then press Ctrl+D it will select the next same word. Then if you type, it will replace all of them at once. You can also use Alt+Shift+Arrow keys to select a "column" of text over multiple lines

i have the subscription of ChatGPT 4 plus. i have just put your code in my directory and execute "chatbot_without_library.php".
it gives me following error: "Fatal error: Uncaught Exception: Error in OpenAI request: The model `gpt-4-0613` does not exist or you do not have access to it. " i am Newby in ChatGPT. Please help me how to resolve this issue.

[@unconv]

ChatGPT Plus subscription is separate from the GPT-4 API access. You might still not have access to GPT-4 API. Try changing the model to `gpt-3.5-turbo` or try `gpt-4` without the 0613 extension.
