• If you want to display the view, also install the Graphviz tool, the installation method is not verbose

  Use
• Key two points to use:
  • The first is whether Runid is generated correctly
  • Visit http://localhost/ddd/xhprof/xhprof_html/index.php
    You can see the log generated by each request in the form of a list, click to see the relevant performance analysis data

Problems encountered

• Because some HTML files and PHP files in the xhprof are to be called by the project, while the xhprof is quite a small framework, it is also possible to run it in the WWW root directory or to customize the configuration
• When you set the cache file location, you should pay attention to the file permissions, or it will cause the xhprof not to go in and cause error.
