title: Why might a file only be partially uploaded?
body: <p>Why might a file only be partially uploaded? </p>
  
  <p>I am improving error-handling in my PHP file upload script and am trying to figure out how to handle UPLOAD_ERR_PARTIAL properly.</p>
  
  <p>Should I prompt the user to try uploading the file again, or should I inform them that there is a more severe problem which is preventing them from uploading a possibly legitimate file?</p>
