Let’s say current URL is: http://example.com/wp-content/plugins/my-plugin/includes/
```
echo plugin_dir_url( __FILE__ ).'images/placeholder.png';
```
will output: http://example.com/wp-content/plugins/my-plugin/includes/images/placeholder.png
```
echo plugin_dir_url( __DIR__ ).'images/placeholder.png';
```
will output: http://example.com/wp-content/plugins/my-plugin/images/placeholder.png

- Let’s say current URL is: http://example.com/wp-content/plugins/my-plugin/includes/pages/ echo plugin_dir_url( __FILE__ ).'images/placeholder.png'; will output http://example.com/wp-content/plugins/my-plugin/includes/pages/images/placeholder.png echo plugin_dir_url( __DIR__ ).'images/placeholder.png'; will output http://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. — By Gardian — 6 months ago

Basic Example

/**
 * Include CSS file for MyPlugin.
 */
function myplugin_scripts() {
    wp_register_style( 'foo-styles',  plugin_dir_url( __FILE__ ) . 'assets/foo-styles.css' );
    wp_enqueue_style( 'foo-styles' );
}
add_action( 'wp_enqueue_scripts', 'myplugin_scripts' );

Would echo:

http://example.com/wp-content/plugins/my-plugin/assets/foo-styles.css

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. — By Mehbub Rashid — 3 years ago
