title: Handling plupload's chunked uploads on the server-side
body: <p>When I use plupload to chunk files (setting option <code>chunk_size</code>), I get a separate PHP request for each chunk. Looking at <code>$_FILES</code> variable, each chunk is of type <code>"application/octet-stream"</code>. </p>
  
  <p><strong>Is there any simple, standard and comfortable way how to combine these pieces in PHP at server-side?</strong></p>
  
  <p>With sanity guaranteed (e.g. when one of the pieces is missing etc.).</p>
