Answer 1

I agree with the above answer, but only want to describe if user getting error in php using nlp google:

useApplicationDefaultCredentials();
# Your Google Cloud Platform project ID
$projectId = 'nlp-project-nname'; //your project name

# Instantiates a client
$language = new LanguageClient([
    'projectId' => $projectId
]);

# The text to analyze
$text = 'Sachin Tendulkar';



# Detects the sentiment of the text
$annotation = $language->analyzeSentiment($text);
$sentiment = $annotation->sentiment();
echo "
";
print_r($annotation); die;

echo 'Text: ' . $text . '
Sentiment: ' . $sentiment['score'] . ', ' . $sentiment['magnitude'];
?>
