Not really. Think about how much time you're spending now into trying to figure out why your destructor is not being run vs just re-factoring the code to do: $storage->detach($client); $client->cleanup(); My view on the matter is one should for the most part limit destructors to things that are good to do, but don't necessarily need to be done with specific timing/ugency. I rarely ever use a destructor in most of my code. When I do, it's usually for just cleaning up resources (file handles, curl handles, image handles, etc).

Don't download and install manually. Use your distro's repositories. They exist specifically so you can use them.
