• If you want to display the view, also install the graphviz tool, the installation method is not long-winded

  use

• Two key points to use:
  • The first is whether the runid is correctly generated
  • Visit http://localhost/ddd/xhprof/xhprof_html/index.php
    to see the log generated by each request in the form of a list, click on it to see the relevant performance analysis data

problems encountered

• Because some html files and php files in xhprof are to be called by the project, and xhprof is also quite a small framework, so to run it, you need to put it in the www root directory, or you can customize the configuration
• When setting the storage location of the cache file, pay attention to the permission of the file, otherwise it will cause the xhprof to not be stored and an error will be reported
