我可以手动在xdebug分析器上说开始在特定位置进行分析吗?

问题描述

我已经在我的XAMPP安装中启用了xDebug分析，并且工作正常.

I already have enabled xDebug profiling in my XAMPP installation and it works fine.

现在我想问一下，是否有一种方法可以在我的源代码中说何时开始使用xDebug进行性能分析.

Now I like to ask if there is a way to say from within my source code when to start profiling with xDebug.

更具体地说，我想创建一个WordPress插件，我想说的是，从插件的起点开始分析，并在插件的终点停止分析.

More specific, I'd like to create a WordPress plugin, and I'd like to say, start profiling from the start point of the plugin and stop profiling at the end point of the plugin.

有可能吗?

注意:以上仅是示例.它可能是CakePHP插件，也可能是我可能需要剖析的新PHP类

Note: The above is just an example. It can be a CakePHP plugin or a new PHP Class that I may need to profile

推荐答案

每您实际上无法在运行时启用/禁用(例如，每个函数调用).

Per How to Turn On/Off Xdebug Profiling at Runtime? you can't actually enable/disable at runtime (for example per function call).

您可以为每个请求有选择地启用探查器，通常更好.要实现此行为，请设置以下设置:

You can selectively enable profiler per request, which is generally better.To achieve this behaviour set those settings:

xdebug.profiler_enable_trigger=1
xdebug.profiler_enable=0

请注意，我们禁用了探查器，仅启用了触发器.从您的浏览器传递XDEBUG_PROFILE = 1

Note that we disable profiler and only enable the trigger.From your browser pass XDEBUG_PROFILE=1

http://example.com/file.php?XDEBUG_PROFILE=1

您也可以在POST或COOKIE中传递此参数.有关更多信息，请检查

You may also pass this parameter in POST or COOKIE. For more info check
