title: How to process <input type="file" name="test1[f]" /> in PHP?
body: <p><code>var_dump($_FILES)</code> gives the following:</p>
  
  <pre><code>array
    'test1' =&gt; 
      array
        'name' =&gt; 
          array
            'f' =&gt; string 'ntuser.dat.LOG' (length=14)
        'type' =&gt; 
          array
            'f' =&gt; string 'application/octet-stream' (length=24)
        'tmp_name' =&gt; 
          array
            'f' =&gt; string 'D:\wamp\tmp\php223.tmp' (length=22)
        'error' =&gt; 
          array
            'f' =&gt; int 0
        'size' =&gt; 
          array
            'f' =&gt; int 0
  </code></pre>
  
  <p>Why is http designed this way?How can I process the array efficiently(sometimes means no looping?) so I can get the file by <code>$_FILES['test1']['f']</code>?</p>
