PHP 클래스 Webmozart\KeyValueStore\SerializingArrayStore
The contents of the store are lost when the store is released from memory.
This store behaves more like persistent key-value stores than
{@link ArrayStore}. It is useful for testing.
사용 중단:
Deprecated as of version 1.0, will be removed in version
2.0. Use the `ArrayStore` with the `SERIALIZE` flag
instead.
