curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// Execute the post
$result = curl_exec($ch);
// Close the connection
curl_close($ch);
// Return the result
return json_decode($result,true);
}

Answer 1

your code is good. I've created my own API key and tried this and works fine. The problem may be in google console.
Please login to https://developers.google.com/apis-explorer/?hl=pl#p/urlshortener/v1/ and try to generate short url there. Google should ask you to authorize the key you created before. After that code should work fine.
