Строка выполнения командной строки в PHP

Это хороший индикатор выполнения для cli:

Другие ответы кажутся слишком сложными. Мое решение состоит в том, чтобы просто выполнить эхо \ 033 [0G escape-последовательность перед следующим обновлением и переместить курсор обратно в начало.

 function progressBar($done, $total) { $perc = floor(($done / $total) * 100); $left = 100 - $perc; $write = sprintf("\033[0G\033[2K[%'={$perc}s>%-{$left}s] - $perc%% - $done/$total", "", ""); fwrite(STDERR, $write); } 

Вызов функции в первый раз выводит индикатор выполнения, и каждый последующий вызов перезаписывает последнюю строку с новой индикацией выполнения.

EDIT: я изменил эхо-сигнал \ r на escape-последовательность \ 033 [0G, и теперь это должно работать на OSX, а также на Linux / Unix.

EDIT 2: Исправлена ​​возможная ошибка в строке 3 в соответствии с предложением @tbjers.

EDIT 3: Обновлен с новой версией, которая печатает на STDERR, а теперь также на GitHub: https://github.com/MacroMan/PHPTerminalProgressBar

Это улучшает предыдущий ответ, который обрабатывает терминальные изменения и использует 2 строки вместо 1. Первая строка – это информация, например, время / процент второй строки – индикатор выполнения.

Я не знаю, почему у вышеуказанного кода есть лицензия, я просто копирую ее, чтобы быть в безопасности. Ниже приведен код без лицензии. Бесплатно для использования в любых целях.
