title: Content-Transfer-Encoding in file uploading request
body: <p>I'm trying to upload file, using XMLHTTPRequest, and sending this headers:</p>
  
  <pre><code>Content-Type:multipart/form-data, boundary=xxxxxxxxx
  
  --xxxxxxxxx
  Content-Disposition: form-data; name='uploadfile'; filename='123_logo.jpg'
  Content-Transfer-Encoding: base64
  Content-Type: image/jpeg
  /*base64data*/
  </code></pre>
  
  <p>But on server side PHP ignore header "Content-Transfer-Encoding: base64"
  and write  base64 undecoded data directly into the file!</p>
  
  <p>Is there any way to fix it?</p>
  
  <p>p.s. it is very important to send data using base64</p>
