Only use host name and remove trailing spaces

First of all, your work is great. It is the only nofollow plugin that is working right now for me but I had an issue recently with regards to having WordPress installed in a seperate folder on the page, like this https://www.example.com/blog/.

Plugin works only for the domain with /blog but anything on the root domain receives a rel=nofollow.

Propose to add an optional feature to only get hostname if required.

For people interested in overriding the function. I added two lines to make it work for me.

static function auto_nofollow_callback( $matches ) {
  $inside_a = $matches[1];
  $site_link = get_bloginfo( 'url' );
		
  /**
  * overrides site url to get hostname only
  * https://stackoverflow.com/questions/17201170/php-how-to-get-the-base-domain-url/17201261
  */
  $site_link =  parse_url($site_link);
  $site_link = $site_link['scheme']."://".$site_link['host'];

  if( strpos( $inside_a, $site_link ) ) { //internal link
    return "<a$inside_a>"; //the space is already in $inside_a
  }

  if( strpos( $inside_a, 'rel' ) === false ) //already has rel attribute
    return "<a$inside_a rel=\"nofollow\" class=\"".$site_link."\">";
  else
    return "<a$inside_a class>";
}
