Trial by Data - Composer

Summary

Used to manage the installation of third-party PHP libraries.

Used to automate the installation of PHPServer-side scripting language for web development. libraries such as TwigPHP template engine that simplifies the generation of HTML pages., PHPMailerA full-featured PHP library for creating and sending emails., Auryn InjectorA PHP Dependency Injector library to support Inversion of Control design pattern., PhinxA PHP library to automate the implementation of database changes. and PHPUnitA PHP Library for Code Test Automation.
This should aid migration to AWS server as Composer can be run as part of Dev Ops process.
My only hang up is that opportunities to use this tool are relatively few and far between which means I usually have to look up commands each time I use it.
However the commands are simple e.g. composer require phpmailer/phpmailer so its not an issue.
