Symfony 2.8.8 функция дампа php7.1 не работает
Недавно я обновил свой php до 7.1, а symfony до 2.8, и все работает нормально, но функция дампа, когда я пытаюсь ее использовать, я получаю:
Примечание: Обнаружено неверно сформированное числовое значение 500 Внутренняя ошибка сервера - исключение ContextErrorException
В vendor/symfony/symfony/src/Symfony/Component/VarDumper/Cloner/VarCloner.php в строке 298 - } } self::$хэш-маска^=шестнадцатеричный код(substr(spl_object_hash($obj), self::$хэш-набор, PHP_INT_SIZE)); } }
Я не знаю, связано ли это с конфигурацией php или с чем-то еще.

ОБНОВЛЕНИЕ похоже, это исправлено в Symfony 2.8.10.
Предыдущий ответ:
Ну, я нашел не очень хороший ответ, но он работает, поэтому я скопировал класс VarCloner.php из Symfony 3.1.3 и изменил его на моем symfony 2.8, и это сработало! Итак, вот класс, я также вставляю сюда тот, который я пробовал.

Вставьте его в YourProject/vendor/symfony/symfony/src/Symfony/Component/VarDumper/Cloner/VarCloner.php
Итак, если кто-то найдет лучший вариант, пожалуйста, дайте его нам! Спасибо!!
