Php - Composer

About

package manager for php.

It manages package

• on a per-project basis,
• installing them in a directory (e.g. vendor) inside your project. By default it does not install anything globally. It does however support a “global” project for convenience via the global command.

Composer is strongly inspired by node's npm and ruby's bundler.

In a Composer project:

• dependencies are defined in a composer.json file,
• while their specific versions are locked in a composer.lock file.
