1. PHP Foundations for WordPress

This module covers the PHP fundamentals you need before writing theme or plugin code.

Lessons

• PHP Syntax, Variables, and Control Flow — read and write basic PHP in WordPress files
• Arrays, Functions, and WordPress Naming — work with arrays, callbacks, prefixes, and WordPress-style functions
• Includes, Scope, and Error Handling — load files safely and avoid common PHP runtime mistakes
