因此，目前我有以下代码，它显示了从主题加载的所有php文件的列表。那么，我如何编辑它以显示所有php文件或仅显示插件文件呢？

功能。php

class IncludedPartGrabber
{

  private $main;
  private $root;
  private $switch = false;

  public function setup($template)
  {
     $this->root = wp_normalize_path(get_theme_root()); // theme folder
     $this->main = wp_normalize_path($template); // main template

     return $template;
  }

  public function grab()
  {
    return array_filter(get_included_files(), array($this, \'filter\') );
  }

  private function filter($file)
  {
    $norm =  wp_normalize_path($file);
    if ($norm === $this->main)
        $this->switch = TRUE; // after main template all files are good to be included

    return $this->switch && strpos($norm, $this->root) === 0; // true if file is in theme dir
  }
}

$grabber = new IncludedPartGrabber;

add_action(\'template_include\', array($grabber, \'setup\'));

add_action(\'wp_footer\', function() use($grabber) {
  echo \'<pre>\';
  print_r($grabber->grab()); // see your footer :)
  echo \'</pre>\';
});

<pre><?php print_r($GLOBALS[\'grabber\']->grab()); ?></pre>
