Multi-Channel Tone Analysis in PHP with Amazon Comprehend

You will update an AWS Lambda function to use Amazon Comprehend for tone analysis of a conversation's content, which is then stored in an RDS MySQL database instance. You need a Vonage API account and have access to the nexmo-community repos to complete this tutorial. To deploy the app, you'll update the index.php file with new code that includes sentiment analysis functionality and deploy it to AWS Lambda. The updated code will store the tone analysis results in the conversations table of the RDS database instance. With the changes made, your app is now ready to include tone analysis for future conversations.
