title: The keyword "use" in PHP gives a "Parse error: syntax error, unexpected T_STRING"
body: <p>I want to use this <a href="https://github.com/jenssegers/php-proxy" rel="nofollow">php proxy</a> script. I downloaded the zip, extracted the content and uploaded it to the server. I created a new index.php file and copied the code from the lib's example into it.</p>
  
  <p>(Note: I am on PHP version 5.2.17-nmm2)</p>
  
  <p>The lib requires Symphony so I uploaded that as well into the same directory. When I run the script, I get:</p>
  
  <blockquote>
    <p>Parse error: syntax error, unexpected T_STRING, expecting
    T_CONSTANT_ENCAPSED_STRING or '(' in index.php on line 3</p>
  </blockquote>
  
  <pre><code>&lt;?php
  
  use Proxy\Factory;
  use Proxy\Response\Filter\RemoveEncodingFilter;
  use Symfony\Component\HttpFoundation\Request;
  
  require 'vendor/autoload.php';
  
  // Create the proxy factory.
  $proxy = Factory::create();
  
  // Add a response filter that removes the encoding headers.
  $proxy-&gt;addResponseFilter(new RemoveEncodingFilter());
  
  // Create a Symfony request based on the current browser request.
  $request = Request::createFromGlobals();
  
  // Forward the request and get the response.
  $response = $proxy-&gt;forward($request)-&gt;to('http://example.com');
  
  // Output response to the browser.
  $response-&gt;send();
