2. “Composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.” https://getcomposer.org/ https://packagist.org/

6. composer.json and composer.lock and composer install and composer update • composer install • installs everything if .lock file doesn’t exist, writes .lock file. • subsequently, brings everything up to date with what’s in the .lock file. • composer update • brings everything in your .json up to date, and updates the .lock file. • Always run composer install on the server. • Composer sees that .json and .lock match, installs everything. • This can be confusing.
