title: file_get_contents() suddenly not working
body: <p>This is all of my code:</p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
  &lt;form&gt;
  Playlist to Scrape: &lt;input type="text" name="url" placeholder="Playlist URL"&gt;
  &lt;input type="submit"&gt;
  &lt;/form&gt;
  
  
  &lt;?php
  
  if(isset($_GET['url'])){
  
          $source = file_get_contents($_GET['url']);
          $regex = '/&lt;a href="(.*?)" class="gothere pl-button" title="/';
  
          preg_match_all($regex,$source,$output);
          echo "&lt;textarea cols=100 rows=50&gt;";
          $fullUrl = array();
          foreach($output[1] as $url){
                  array_push($fullUrl,"http://soundcloud.com".$url);
          }
          $final = implode(";",$fullUrl);
          echo $final;
          echo "&lt;/textarea&gt;";
  }else{
          echo "borks";
  }
  
  
  ?&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Yesterday, it worked fine.
  What the code <em>should</em> do is:
  Take a Soundcloud URL, extract the individual songs, and then print them like song1;song2;song3</p>
  
  <p>Again, this worked fine yesterday, and I haven't changed anything since, I think...</p>
  
  <p>I have tried to comment the other code out, and just keeping $source = file_get_contents($_GET['url']); and echoing $source, but it returned blank, which makes me think it is a problem with file_get_contents.</p>
  
  <p>If you have any idea on why this is happening, I would appreciate hearing it.  Thanks! </p>
