title: Get full path to image from php
body: <p>Hy!</p>
  
  <p>I parse a website with simplehtml dom to get all links from the pictures.</p>
  
  <p>The problem is that the link is like "/pics/bla.jpg".</p>
  
  <p>I have the full path from the website like "http://xxx.xxx/blob/gulsch".</p>
  
  <p>Now i want to get the full image link from the image (<strong>link root + /pics/bla.jpg</strong>) (no concat)
  like: <a href="http://xxx.xxx/pics/bla.jpg" rel="nofollow">http://xxx.xxx/pics/bla.jpg</a></p>
  
  <p>This should work for many websites</p>
  
  <p>I tried it with explode() </p>
  
  <pre><code>$root = explode("/", $link);
  echo $root[2];
  </code></pre>
  
  <p>I never get it working.</p>
  
  <p>Please help.</p>
