Where should this code be deployed?? I'm not able to run it on lampserver

Thank you for the sample, it works like a charm! ;)

Thanks for sharing this !

You, my friend, are a LifeSaver.Thanks

how to set destination ?

I wrote a package to download / get local file and upload to Google Cloud Storage, maybe it help as well:
https://github.com/jeansouzak/duf
You can send a local file or external resource:

use JeanSouzaK\Duf\Duff;
use JeanSouzaK\Duf\Prepare\WebResource;
use JeanSouzaK\Duf\Prepare\LocalResource;

$duf = Duff::getInstance(Duff::GOOGLE_CLOUD_STORAGE, [
    'project_id' => 'storage-test-227305',
    'key_path' => '/home/env/storage-test-227305-8472347a39489.json'
]);

// - Chaining example -
$uploadResults = $duf->prepare([
    new LocalResource('imagem', '/home/test/images/test.jpg'),
    new WebResource('teste.png', 'https://dummyimage.com/600x400/000/fff')
])->download()->addBucket('your-bucket-name')->upload();
