我试图将Zend_Log(与Zend_Log_Writer_Stream)的实例存储到Zend_Cache(优选)或Zend_Registry(回退)，但使用自定义助手作为抽象层而不是直接访问。
- 除了直接使用Zend_Registry，每次Zend_Log_Writer_Stream的_stream属性消失。
我在下面附上了我的代码以及它生成的输出。
我没有遵循这些链接，因为我有另一个作家Zend_Log_Writer_Database写到一个单独的数据库比应用程序，所以我需要初始化。现在我已经把它注释掉了

- Zend_Log在存储时不应该序列化。
- Zend_Cache不是一个选项，因为它需要对象被序列化，因为它只存储字符串。
- Zend_Registry没有通过helper类工作，因为代码正在进行一些序列化。
简而言之:
- 使用Zend_Registry来存储对象
- 存储在Zend_Registry 时不序列化
