有没有办法知道哪个PHP文件在Wordpress中生成了一个页面？

Question

I am trying to make some changes to PHP files in Wordpress, but it is taking me a long time to find which PHP file to edit. Is there a way to know which PHP file generated a given page? Thanks!

More information: I understand the basic outline of Wordpress templates like header.php and single.php. However, I am having a hard time walking through the many theme-specific template files and finding which one serves what purpose. Specifically, I am looking at a generated webpage and attempting to edit it. And I am resorting to inserting

tags inside each of the probable template files until I find the right one. Is there a way, perhaps through dev-tool, to see which php file generated the DOM?

It is possible to get a list of all the included files through the get_included_files() function in PHP. Here is a PHP script to set in the footer.php file of your template :

// echo '<!--'; // you can display this code or show it in an HTML comment
$files = get_included_files();
if ($display_only_theme_files === true) {
  $theme_folder = get_template_directory();
  foreach ($files as $key => $file) {
    if (strstr($file, $theme_folder) === false) {
      unset($files[$key]);
    }
  }
}
print_r($files);
// echo '-->'; // you can display this code or show it in an HTML comment

This script will show you all the included files related to your template. In other words, you will have the possibility to know which file template is used.

Please, be sure to use this code only on your development mode and to delete it when you will be in production.
