Zend framework 在Zend_缓存/Zend_注册表中存储Zend_日志实例（带/不带自定义帮助程序）

我正在尝试将Zend_Log的一个实例（带有Zend_Log_Writer_Stream）存储到Zend_缓存（最好）或Zend_注册表（回退），但将自定义助手作为抽象层而不是直接访问

问题

• 除非直接使用Zend_注册表，否则每次Zend_Log_Writer_Stream的_Stream属性都会消失

我在下面附上了我的代码以及它生成的输出

我没有这样做，因为我有另一个writer Zend_Log_writer_数据库，它写入到一个独立的数据库而不是应用程序，所以我需要初始化它。现在我已经把它注释掉了

Zend_日志在存储时不应序列化
Zend_缓存不是一个选项，因为它需要序列化对象，因为它只存储字符串
Zend_注册表无法通过helper类工作，因为由于代码的原因，正在进行一些序列化。删除该项修复了该问题

简言之：


使用Zend_注册表存储对象
在Zend_注册表中存储时不要序列化
