But i got the solution by inserting the content type in putObject

$requestHeaders = array(
‘Content-Type’ => ‘application/octet-stream’,
‘Content-Disposition’ => ‘attachment; filename=${filename}’
);

$params = S3::getHttpUploadPostParams(
$bucket,
$path,
S3::ACL_PUBLIC_READ,
$lifetime,
$maxFileSize,
201, // Or a URL to redirect to on success
$metaHeaders,
$requestHeaders,
false // False since we’re not using flash
);
