title: PHP pass a var into $_FILES inside function
body: <p>I am working on an admin area that will have file uploads on several pages.  Regardless of the name of the form field I want to do some specific processes, but I'm a bit stuck on how to do this in a function.  I have the code below, which I knew going in wouldn't be correct, but I'm not sure how to achieve what I'm trying to do.</p>
  
  <pre><code>function fileprocessor ($file)
  {
      echo $_FILES['$file']['tmp_name'];
  }
  </code></pre>
  
  <p>Any thoughts?</p>
