How I Built a Production-Ready AI Agent on PHP, cPanel, and Gemini Flash
Most AI agent tutorials assume you are starting from a modern stack: Python, Docker, Redis, background workers, vector databases, and cloud infrastructure already built for orchestration.
That is useful if you are working inside a mature platform team. But a lot of real software still runs on plain PHP, MySQL, and cPanel, and many builders still need to ship useful AI features without first rebuilding their entire infrastructure.
That was the challenge behind this project.
I wanted to build an AI agent that could:
- accept a user request,
- decide whether it needed a tool,
- execute that tool in PHP,
- store conversation state in MySQL,
- and keep reasoning until it produced a final answer.
In this article, I will walk through how I built that system using:
- PHP for orchestration
- MySQL for memory
- Gemini Flash for reasoning and function calling
- cPanel for deployment on standard shared hosting
The point is not...
