Building a Chatbot with OpenAI ChatGPT-API and PHP
Are you interested in building a chatbot powered by an AI language model? Look no further than this ChatGPT clone project! In this article, we’ll walk through the process of setting up and running the ChatGPT clone, which allows users to chat with an AI language model trained by OpenAI.
What is ChatGPT?
ChatGPT is an AI chatbot that uses OpenAI’s GPT-3 language model to generate responses to user input. The chatbot is built using PHP and the OrhanErday/OpenAI library, which provides an easy-to-use interface for communicating with the OpenAI API.
Getting Started
Before running this project, you’ll need to make sure you have the following installed:
- PHP 7.4 or later with SQLite3 enabled
- Composer
- An OpenAI API key
To get started, follow these steps:
- Clone the repository to your local machine by running
git clone https://github.com/orhanerday/ChatGPT.git
. - Navigate to the project directory by running
cd ChatGPT
. - Install the OrhanErday/OpenAI library by running
composer require orhanerday/open-ai
. - Set your OpenAI API key as the
$open_ai_key
variable inevent-stream.php
. - Start the PHP built-in web server by running
php -S localhost:8000 -t .
. - Open your web browser and go to
http://localhost:8000
.
That’s it! You should now see the ChatGPT clone interface, where you can chat with the OpenAI language model.
Using Docker
If you prefer to use Docker to run the ChatGPT clone, you have two options:
Method I:
- Clone the repository to your local machine by running
git clone https://github.com/orhanerday/ChatGPT.git
. - Navigate to the project directory by running
cd ChatGPT
. - Build the Docker image by running
docker build -t chatgpt .
. - Run the app by running
docker run -p 8000:8000 -e OPENAI_API_KEY=<YOUR_OPENAI_API_KEY> chatgpt
. - Open your web browser and go to
http://localhost:8000
.
Method II:
- Pull the Docker image from Docker Hub by running
docker pull orhan55555/chatgpt

docker run -p 8000:8000 -e OPENAI_API_KEY=<YOUR_OPENAI_API_KEY> orhan55555/chatgpt
. - Open your web browser and go to
http://localhost:8000
.
Chat History
This project saves chat history using cookies by default. If you want to change this to use authentication instead, you can modify the code in index.php
to save chat history in a database or other storage mechanism.
