title: How to get the absolute path of a file in a Symfony2 controller?
body: <p>I want to send an email with an attachement so therefore I need the absolute path to the pdf file. </p>
  
  <p>I tried the flowing code in the controller:</p>
  
  <pre><code>$this-&gt;get('templating.helper.assets')-&gt;getUrl('MyDoc.pdf', 'doc');
  </code></pre>
  
  <p>But this returns:</p>
  
  <pre><code>/bundles/MyBundle/doc/MyDoc.pdf?v=1
  </code></pre>
  
  <p>This is the path without the domain for web access. But I need the real path starting the root of the disk, like example below. How is this possible? Thanks.</p>
  
  <pre><code>/home/MyAccount/public_html/web/src/company/MyBundle/Resources/public/doc/MyDoc.pdf
  </code></pre>
