Я получаю контент через Amazon Web Services (например, описания продуктов).Поскольку контент от Amazon часто размечается очень плохо, в конечном итоге он портит макет моих веб-страниц.Итак, я придумала функцию «санации» содержимого с помощью HTML Tidy.
Странная вещь в том, что когда я тестирую его отдельно от приложения, кажется, что все работает нормально.Но в моем приложении (работающем на CodeIgniter) функция, кажется, возвращает нечетные символы.
Код ниже - мой тестовый скрипт.Он выводит то, что мне нужно.
В своем приложении я извлекаю описание из базы данных, очищаю его, а затем отображаю на своей веб-странице.Например, после очистки, document’s (вы можете увидеть это слово в примере ниже) становится document’s (опять же, только в реальном приложении; не в тестовом коде. Обе функции идентичны).
Есть идеи, почему?Вот моя тестовая функция:
$amazon_content = <<<AMAZON
