title: Get part of the TItle in Wordpress with a function
body: <p>I'm struggling in creating a shortcode that will get part of the Page title.</p>
  
  <p>I have already created (thanks to someone in StackOverflow...)</p>
  
  <pre><code>function myshortcode_title( ){
     return get_the_title();
  }
  add_shortcode( 'page_title', 'myshortcode_title' );
  </code></pre>
  
  <p>but I need also to get part of the Title and it has to get only last chars:</p>
  
  <p>Title: Assistenza Caldaie Vaillant</p>
  
  <p>I need to get only <strong>Vaillant</strong> (Assistenza Caldaie is always the same).</p>
  
  <p>Could someone help me?</p>
  
  <p>Thanks,
  Stefano</p>
