PHP developers build ambitious applications with Laravel and Symfony every day — but the moment AI enters the picture, they're told to reach for Python. This book proves that's unnecessary.

Building AI Applications with PHP walks you through creating two complete, production-grade AI applications from scratch: an intelligent customer support agent with Laravel and an AI content generation pipeline with Symfony. Both use PapiAI, an open-source PHP library with zero runtime dependencies, support for 10 LLM providers, and a proper agentic runtime.

You'll learn every aspect of AI application development that matters in production: streaming responses in real time, giving agents tools that query your database, managing conversation memory across requests, validating structured output with schemas, building RAG pipelines with embeddings and vector search, processing tasks asynchronously with queues, defending against prompt injection, controlling costs, and deploying with confidence.

This isn't a tour of API endpoints. It's a guide to the architecture, patterns, and hard-won lessons that separate a demo from a deployable product — written entirely in the language you already know.
