Framework Deep Dive

Welcome to the Framework Deep Dive

A complete walkthrough of DALT.PHP's internals. Every file, every line, explained in clear language. This is where you learn how web frameworks actually work by reading real, production-quality code.

What You'll Learn

This deep dive covers the complete request lifecycle:

1. Entry Point - How requests enter and bootstrap the framework
2. Routing - How URLs map to controllers and middleware runs
3. Container & Database - How dependency injection and queries work
4. Sessions - How data persists across requests and flash messages work
5. Authentication - How login, logout, and password verification work
6. Views - How templates render and Vite integrates

Who This Is For

Read this if you want to:

• Understand how routing, middleware, and sessions work under the hood
• See how a web framework is built from scratch
• Learn backend patterns by reading clear, documented code
• Prepare for contributing to DALT or building your own framework

How to Read This

Each section includes:

• Overview - What the code does and why
• Line-by-Line - Detailed walkthrough with explanations
• Key Concepts - Important patterns and decisions

The entire framework is ~1,000 lines. You can read it all in an afternoon and understand every piece.
