видео Управление оболочкой командной строки в PHP

Linux - Терминал в Ubuntu, shell, bash, базовые команды, права доступа к файлам.

Этот пакет php-классов может быть использован для создания и управления оболочкой командной строки в чистом PHP.



Он может читать команды из стандартного ввода и выполнять опознанные команды с помощью отдельных классов.

Список распознаваемых команд можно настроить путем регистрации PHP классов, которые реализуют новый пользовательский обработчик команды.

Основной класс запускает цикл обработки событий, который отображает подсказки, читает команды из стандартного ввода и отправляет вызовы команд классам для последующей обработки этих команд. Цикл заканчивается, когда команды выполнены.


Работа в командной строке [GeekBrains]

Несколько встроенных пользовательских классов обработки команд, предоставлены для выполнения действий, таких как: перечисление всех зарегистрированных команд, предоставление справки и примера для использования команды.
