Introduction

What PHP is, where it fits, and how the two build-along tracks relate.

Ladder toward a small JSON HTTP API on PHP's built-in server — install, variables, control flow, functions, and your first endpoint.

Extend the API with a persistence layer — PDO, SQLite or MySQL.

Deployment hardening for the same artifact — php-fpm/nginx, Docker, CI.

A fundamentals deep-dive independent of the artifact ladder — types, OOP, error handling, the standard library.

A second build-along artifact — a small command-line PHP tool with no framework.
