The document discusses dependency management in PHP projects. It describes existing solutions like PEAR and tools used by other languages. It then focuses on Composer, a dependency manager created specifically for PHP. Composer allows defining dependencies in a composer.json file and downloading/installing them. The document shows how to use Composer to manage dependencies for Zend Framework 2 projects and modules.

10. Composer

PEAR. Why NOT?

Composer. Why?
− Created for Dependency management
− Separate storage & Package metadata
− Support existing infrastructure
− Dist & Source
− Extendable
− Autoload Support

11. Composer. Architecture

Package

Repository – package meta data
− Composer, Pear, VCS, etc

Downloader
− Archive, VCS, Pear

Installer
− Library, Project

Autoload
− PSR-0, ClassMap
