Add contentDisposition in putobject in php as 'ContentDisposition' => 'attachment',

$result = $client->putObject(array(
  'Bucket'     => $bucket,
  'Key'        => $fileName,
  'SourceFile' => $fileTempName,
  'ContentDisposition' => 'attachment',
  'Metadata'   => array(
    'Foo' => 'abc',
    'Baz' => '123'
  )
 ));
