Week 1: PHP 8 syntax, arrays, functions, classes, strict types
Week 2: Composer, PSR autoloading, PHPUnit basics
Week 3: Laravel — routes, controllers, Eloquent, migrations, Blade
Week 4: Either a Laravel CRUD app or a custom WordPress plugin, deployed

php -v                                  # check PHP 8.x is installed
composer --version
composer create-project laravel/laravel orders-app
cd orders-app
php artisan make:model Order -m          # model + migration
php artisan migrate
php artisan serve                        # http://127.0.0.1:8000

Portfolio pieces for PHP work
☐ A Laravel CRUD app with authentication
☐ A small WordPress plugin using hooks
☐ A performance or bug-fix write-up on a demo site
☐ README for each: what, why, how to run
Pitch: "Python developer who also builds and fixes PHP sites"
