Building Resilient PHP Applications with an Event-Driven Mindset

Event Sourcing is a powerful architectural pattern that captures application state changes as a sequence of immutable events, enabling robust, auditable, and scalable systems. In this beginner-friendly talk, we’ll demystify event sourcing and show how PHP developers can implement it effectively to solve real-world problems. We’ll explore the core philosophy of event sourcing - storing "what happened" instead of "what is" - and its benefits, including complete audit trails, simplified debugging, and flexibility for future features. Using practical PHP examples, we’ll walk through a simple event-sourced system with a relational database (e.g., MySQL) in a Laravel example. Attendees will learn key concepts like event stores, aggregates, and how that causes optimized performance. This talk is perfect for developers new to event sourcing or those curious about its practical applications in PHP. By the end, you’ll have a clear understanding of how to start incorporating event sourcing into your projects, whether for e-commerce, financial systems, or complex workflows. Join us to discover how event sourcing can make your PHP applications more resilient and adaptable!
