You want an AI chatbot. You use PHP. Here is the way.

You need these tools:

• PHP 8.1 or higher
• Composer
• OpenAI API key

Start with the client. Run this command: composer require openai-php/client

Your bot needs memory. Use PHP sessions. This stores the chat history.

Make the bot fast. Use streaming. Server-Sent Events send text in small pieces. Your users see the answer live.

Follow these rules for safety:

• Store your API key in server env variables.
• Use HTTPS for sessions.
• Limit session history to save tokens.
• Add rate limits to stop high costs.
• Catch errors to stop crashes.
