title: Linkedin share-link wrong
body: <p>I'm setting up my own social share box, but I'm having trouble using the linkedin-share option.
  The content inside the link is passed in through php, but I think there's an error in my code    </p>
  
  <p>When I try to manually change the article url inside the share-url, it works fine, but my generated link won't work.    </p>
  
  <p>This is what i wrote inside my code:</p>
  
  <blockquote>
    <p><code>mini=true&amp;url=&lt;?php echo $url;?&gt;&amp;title=&lt;?php echo $title; ?&gt;&amp;summary=&lt;?php echo $excerpt;?&gt;&amp;source=dfib.net"</code></p>
  </blockquote>
  
  <p>and this is how it outputs in the browser:     </p>
  
  <blockquote>
    <p><code>https://www.linkedin.com/shareArticle/?mini=true&amp;url=http://dfib-nieuw.test/attentia-jobsite/&amp;title=Attentia%20jobsite&amp;summary=Hoe%20kan%20je%20deze%20doelgroep%20beter%20aanspreken%20dan%20met%20een%20aantrekkelijke%20website%20die%20alle%20job-%20en%20carri%C3%A8re-info%20overzichtelijk%20weergeeft?&amp;source=dfib.net</code></p>
  </blockquote>
  
  <p>What am I doing wrong here?</p>
