Write to body slowly on guzzle

Question

I'm trying to send data on body, using put request with Guzzle. How can I write data to body, similar to this read command of get message?

while (!$body->eof()) 
{
    $data = $body_origin->read(1024*1024);
}

Something i tried:

$dest_stream = Psr7\Utils::streamFor();
$response_dest = $client_destination->request('PUT', $url_dest, 
[
    'stream' => true,
    'body' => $dest_stream,
    'read_timeout' => 100,
    'Content-Type' => 'application/octet-stream',
    'headers' => 
    [
        'Content-Length' => '0'
    ]
]);

while (!$data_to_send->eof()) 
{
    $data = $data_to_send->read(1024*1024);
    $dest_stream->write($data);
}
