Packagist provides a mechanism for users to publish their packages for others to use.Ĭomposer only works on PHP version 5.3.2 or above, although PHP 5.3.4 or higher is recommended. However, it is also possible to build packages from scratch from original PHP files and functions. Users typically extend these packages or join multiple packages together to form the backbone of their PHP project. Packagist offers a large number of free, ready-to-use PHP packages. This helps avoid instability and compatibility issues.Ĭomposer works in conjunction with Packagist. Composer manages all of these secondary dependencies so all packages and libraries are upgraded at once. Some of these packages might depend on other packages. It then installs the relevant version of the package into the project directory. Composer determines the package version that should be installed. Users declare the libraries they want using the require command that adds a corresponding entry to the composer.json file. However, it does support a “global” project for individuals or small groups who are only working on a single project. Composer does not install any packages globally. All libraries are installed in a designated directory inside the project directory. While doing so, it determines what other systems or PHP packages are required.Ĭomposer manages packages and libraries on a per-project basis, so it is more accurately termed a dependency manager. Users declare the PHP libraries they are using and Composer either installs or updates them as needed. An Introduction to PHP ComposerĬomposer is inspired by programs such as npm, which is used to manage different versions of Node. This guide explains how to install and update Composer and how to use it to install and update packages.

However, it can become difficult to manage the minimum version and dependencies for each package. Due to the increasing complexity of these applications, third-party PHP packages have become increasingly popular.
