Upload multiple large files to s3 using laravel

Anyone knows how to upload large multiple files to s3 with laravel 5? i tried to use streams but it works only for files less than 5M, here is my code:

foreach ($request->file('photos') as $file) {  
  $filename = $file->getClientOriginalName();
  $s3 = \Storage::disk('s3');
  $filePath = '/uploads/' . $filename;
  $stream = fopen($file->getRealPath(), 'r+');
  $s3->put($filePath, $stream);
}

i tried to update settings in my php.ini as well like this but no change

upload_max_filesize = 50M
