Composer is an application-level package manager for the PHP programming language. It provides a standard format for managing with ease PHP-based project dependencies (libraries) and was strongly inspired by Node.js's "npm" and Ruby's "bundler". Use with the [php] tag
Presentation
Composer is an application-level package manager.
Yes, it deals with "packages" or libraries, but it manages them on a per-project basis, installing them inside your project's directory.
By default, it will never install anything globally.
Thus, it is considered a PHP-based project package manager.
