Low level profilers - These are modules which are loaded into the php executable, and therefore are a bit harder to setup, but they provide solid results.
PQP is a code-based profiler. While probably not as accurate as the low-level profilers mentioned above, it may be all you need if you are looking for some simple metrics.
One you can use is xdebug. Also something nice to note is that if you use frameworks. The framework kohana has a build in profiler that even measures your queries.

低级分析器 - 这些是加载到 php 可执行文件中的模块，因此设置起来有点困难，但它们提供了可靠的结果。
PQP 是一个基于代码的分析器。虽然可能不如上面提到的低级分析器那么准确，但如果您正在寻找一些简单的指标，它可能就是您所需要的。

我使用 XDebug 和 WinCacheGrind 来分析 php。
I use XDebug and WinCacheGrind to profile php.

请参阅我公司的（语义设计）PHP Profiler。使用此功能无需对 PHP 服务器进行任何更改。
See my company's (Semantic Designs) PHP Profiler. No changes required to the PHP server are needed to use this.
您可以使用的一个是 xdebug。另外值得注意的是，如果您使用框架。框架 kohana 有一个内置的分析器，甚至可以测量您的查询。

我会选择xdebug。
I'd go for xdebug.
