通常情况下没有进行复位而收集的数据不是很有用，因为计数器的时间跨度较长，包括随着负荷起伏跌宕截然不同的工作负载。

Typically the data collected without a reset is not very useful because the counters span a longer period of time, including drastically different workloads along peaks and valleys in load.

除此之外，SDO还利用PHP的像处理数组那样处理对象的能力来实现对象，包括实现对集成的支持，声明测试和复位。

In addition to this, SDOs also exploit PHP's ability to implement objects that can be manipulated as if they were arrays, including support for iteration, state testing and unsetting.
