Here are some tips you should know when using Composer the dependency manager for PHP. 1. Update only one vendor You want to update only one specific library, without updating all your dependencies?

In this article I will introduce you to another great project, Composer. Maybe you’ve experienced the pain of working on a PHP application which uses third-party libraries and then trying to keep them and their dependencies up to date. If so, Composer can soothe your pain. Composer gets you the libraries you want at the versions you need. And if those libraries use other libraries, it can install those and manage them as well. Dependency management can be a hassle-free experience using Composer. Installing Composer Composer is bundled as an executable Phar archive, so make sure you have the Phar extension enabled in your php.ini file (uncomment extension=phar.so).
I recommend download the latest snapshot of the Composer executable directly from the project’s website. Alternatively, there is an installer script that you can run.

What is a script? # A script, in Composer's terms, can either be a PHP callback (defined as a static method) or any command-line executable command. Scripts are useful for executing a package's custom code or package-specific commands during the Composer execution process. Note: Only scripts defined in the root package's composer.json are executed. If a dependency of the root package specifies its own scripts, Composer does not execute those additional scripts. Event names# Composer fires the following named events during its execution process: Command Events# Installer Events# pre-dependencies-solving: occurs before the dependencies are resolved.post-dependencies-solving: occurs after the dependencies have been resolved.
Package Events# Plugin Events# init: occurs after a Composer instance is done being initialized.command: occurs before any Composer Command is executed on the CLI. Note: Composer makes no assumptions about the state of your dependencies prior to install or update. <? Composer.
