Deep-Dive Path

Read the PHP manual while testing examples locally in a CLI and web-server environment.
Install Composer, add one package, and inspect the generated lock file and autoloading behavior.
Build one small backend using plain PHP or a framework and connect it to a database.
Deploy the app behind Apache or Nginx and document the environment configuration.
