![Cloud Storage
Built in Stream Wrappers allowing use of
file api’s like file_get_contents();
$fp = fopen("gs://my_bucket/some_file.txt", "w");
fwrite($fp, "Hello");
fclose($fp);
$options = [ "gs" => [ "Content-Type" => "text/plain" ]];
$ctx = stream_context_create($options);
file_put_contents("gs://my_bucket/hello.txt", "Hello", 0, $ctx);
