After much frustration and very little documentation that I could find, I thought I'd offer this example of implementation of http_put_file with custom HTTP headers, and the corresponding ReceiveFile.php.

I do an http put with a customized header containing parameters for file processing.

<?php
      $header = array(
                  'file_size'   => $file_size
                , 'file_name'   => $file_name
                , 'md5sum'      => $md5sum
              );

      $URI = 'http://MyDomain.com/ReceiveFile.php';

      if (($f = @fopen($URI,'r'))) {
        fclose($f);
        if ($result = @http_put_file($URI, $file_path, array(
                    headers => array(
                           'X_CUSTOM_PUT_JSON'  => json_encode($header)
                          ,'X_FRUIT'     => 'bananna'
                        )
                  , useragent => 'Magic UnitTests'
                 )
                , $info))) {
          echo str_replace("\n",'<BR>',$result);
        }
        else
           echo 'http failure';
     }
     else
        echo "Can't find URI: [$URI]";
?>

ReceiveFile.php has:
<?php
      $CUSTOM_HEADER = 'HTTP_X_CUSTOM_PUT_JSON';
      $CHUNK = 8192;

      try {
        if (!($putData = fopen("php://input", "r")))
          throw new Exception ("Can't get PUT data.");

        if (!(array_key_exists($CUSTOM_HEADER, $_SERVER)))
          throw new Exception ("Custom header missing.")

        $json = json_decode($_SERVER[$CUSTOM_HEADER], true);
        $this->logParams(__FUNCTION__, $json);
        foreach ($json as $fld => $val)
          $$fld = $val;

    // now the params can be used like any other variable
    // see below after input has finished

        $tot_write = 0;

      // Create a temp file
        if (!($tmpFileName = tempnam("/tmp", "PUT_FILE_")))
          throw new Exception ("Can't create tmp file.");

      // Open the file for writing
        if (!($fp = fopen($tmpFileName, "w")))
          throw new Exception ("Can't write to tmp file");

      // Read the data a chunk at a time and write to the file
        while ($data = fread($putData, $CHUNK)) {
          $chunk_read = strlen($data);
          if (($block_write = fwrite($fp, $data)) != $chunk_read)
            throw new Exception ("Can't write more to tmp file");

          $tot_write += $block_write;
        }

        if ( ! fclose($fp) )
          throw new Exception ("Can't close tmp file");

        unset($putData);

  // Check file length and MD5
        if ($tot_write != $file_size)
          throw new Exception ("Wrong file size");

        $md5_arr = explode(' ',exec("md5sum $tmpFileName"));
        $md5 = $md5sum_arr[0];
        if ($md5 != $md5sum)
          throw new Exception ("Wrong md5");
?>
