   Let’s say current URL is: https://example.com/wp-content/plugins/my-plugin/includes/

   echo plugin_dir_url( __FILE__ ).'images/placeholder.png';

   will output: https://example.com/wp-content/plugins/my-plugin/includes/images/placeholder.png

   echo plugin_dir_url( __DIR__ ).'images/placeholder.png';

   will output: https://example.com/wp-content/plugins/my-plugin/images/placeholder.png

   • Let’s say current URL is: https://example.com/wp-content/plugins/my-plugin/includes/pages/ echo plugin_dir_url( __FILE__ ).'images/placeholder.png'; will output https://example.com/wp-content/plugins/my-plugin/includes/pages/images/placeholder.png echo plugin_dir_url( __DIR__ ).'images/placeholder.png'; will output https://example.com/wp-content/plugins/my-plugin/includes/images/placeholder.png Which is still not the plugin directory, but only one directory above. I’m still searching for a logical function that returns the root of our plugins.

   • plugin_dir_url vs plugin_dir_path difference

     plugin_dir_url( string $file )

     Use it to include your assets (images, css, js etc).

     plugin_dir_path( string $file )

     Use it to include php files.
