fread from a s3 stream always downloads the whole file. This is due to outdated API implementation. Check here for the latest:

http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?RESTObjectGET.html

Here is the new stream_read function which resolve the 1) wrong range header and 2) wrong check for 200 http code:

{{
public function stream_read($count)
{
if (!$this->_objectName) { return false; }

$range_start = $this->_position;
$range_end = $this->_position+$count;

// Only fetch more data from S3 if we haven't fetched any data yet (postion=0)
// OR, the range end position is greater than the size of the current object
// buffer AND if the range end position is less than or equal to the object's
// size returned by S3
if (($this->_position == 0) || (($range_end > strlen($this->_objectBuffer)) && ($range_end <= $this->_objectSize))) {

$headers = "Range:bytes=$range_start-$range_end";

$response = $this->_s3->_makeRequest('GET', $this->_objectName, null, $headers);
$status = (string)$response->getStatus();
if (strpos($status, "20") === 0) { $this->_objectBuffer .= $response->getBody(); }
}

$data = substr($this->_objectBuffer, $this->_position, $count);
$this->_position += strlen($data);
return $data;
}
}}
