Преобразуются двойные ковычки в " и <> в > при записи в файл

Почему то преобразуются двойные ковычки "" в " и <> в > при записи в файл.

Подскажите пожайлуста. Как заставить записывать ковычки (одиночные, двойные) и стрелочки вместо ",> в текстовый файл на сервере?

Строка 16 - $htacces = str_replace("&", "&", $this->request->post['htacces']);

При добавлении $htacces = str_replace("&amp;", "&", "&quot;", "\"", "&lt;", "<", "&gt;", ">", $this->request->post['htacces']); выдает ошибу - Only variables can be passed by reference in
