Как распаковать zip-папку с помощью php-кода

Хочу разархивировать директории.

Это означает, что у меня есть имя заархивированного каталога с xxx.zip. В manuall я щелкнул правой кнопкой мыши заархивированный каталог и извлек папку, затем я получил распакованный каталог с именем xxx, а также в этом каталоге есть тот же каталог xxx. В подпапке будет содержаться файлы.

Это означает, что xxx-> xxx-> files - это хейрарчи разархивированной папки.

Итак, на моем сайте я хочу распаковать каталог, используя PHP-код.

Как я могу это сделать? Мне нужна только xxx->files, а не xxx->xxx->files структура.

Как я могу это сделать?

См. Этот http://www.php.net/manual/en/ziparchive.extractto.php

$zip = new ZipArchive;
if ($zip->open('E:\pathto\zip\ashok_subedi.zip') === TRUE) {
    $zip->extractTo('E:\pathto\extrac\myzip');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}

Вы можете загрузить этот файл на свой веб-сервер и запустить его. Вам будет предложено выбрать zip-файл для распаковки, и вы можете указать путь, по которому вы хотите распаковать. Если вы хотите разархивировать файл в текущем месте, просто оставьте путь разархивирования пустым. По завершении распаковки вы получите отзыв.
