Wordpress Plugin Fundamentals

This is a solid foundation for building WordPress plugins the modern way: PHP 8.3+, OOP with PSR-4 autoloading, and WordPress 6.7+ APIs. It covers the three-layer security model (sanitize, validate, escape), Composer setup with WPCS and PHPUnit, and proper hooks integration. You'd reach for this when you're done with tutorial-style procedural code and want to structure plugins like actual applications. The 179 installs suggest it's seeing real use. Worth noting it assumes you're comfortable with modern PHP tooling, so if you're still writing functions.php code, expect a learning curve.
