Установка Composer на Ubuntu 16.04

Composer — это пакетный менеджер уровня приложений для языка программирования PHP, который предоставляет средства по управлению зависимостями в PHP-приложении. Composer разработали и продолжают поддерживать два программиста Nils Adermann и Jordi Boggiano. Composer произвел революцию в управлении пакетами в PHP и помог разработчикам по всему миру создавать независимый от фреймворков и разделяемый код.
