Результатом должен быть чистый SWF-файл.
Конечно, это возможно, но вам нужно будет прочитать данные файла и понять структуру файла, чтобы узнать, где хранится файл actionscript.
вы можете использовать собственные функции PHP, такие как
Наряду с другими бинарными инструментами, такими как
Чтобы управлять двоичными данными, я предлагаю вам начать со следующей ссылки, чтобы понять сложность этого:
Вот довольно простой класс, который позволяет вам читать данные из SWF или сжатого SWF-файла:
