How do I get the path alias without the language code?

Question

Suppose I have an alias like http://www.example.com/en/the-new-webpage.html.

I want to get the the-new-webpage.html part in hook_preprocess_html(). The language code might change into 'ja' or some other code due to the language availability. So I can't get the URL and pass it to str_replace() to replace the language part. Is there a function or a way to get the alias part without the language code?

Since you just need the last part of the path, you can use the following code in a hook_preprocess_html() implementation.

$current_path = \Drupal::service('path.current')->getPath();
$alias = \Drupal::service('path.alias_manager')->getAliasByPath($current_path);
if (basename($alias) == 'the-new-webpage.html') {
  // Your code here
}

Starting with Drupal 8.8.0, some Drupal core service has been renamed, as described in The Path Alias core subsystem has been moved to the "path_alias" module. As consequence of that, in Drupal 8.8.0, Drupal 9.x, and Drupal 10.x, the path.alias_manager service has been replaced by the path_alias.manager service.
The previously shown code needs to be changed to the following one.

$current_path = \Drupal::service('path.current')->getPath();
$alias = \Drupal::service('path_alias.manager')->getAliasByPath($current_path);
if (basename($alias) == 'the-new-webpage.html') {
  // Your code here
}

The path.current service has not been renamed, neither in Drupal 9.x nor in Drupal 10.x.
