Sentiment Analysis using IBM Watson Tone Analyzer in PHP

Sentiment analysis is crucial in understanding the emotions and intentions behind text-based communications, such as SMS messages. It can help bridge the gap between what we say and what we mean, particularly in professional settings where tone can easily be misinterpreted. Leveraging IBM Watson's Tone Analyzer service, a PHP application can be set up to analyze the sentiment of incoming SMS messages using Vonage's SMS service, demonstrating how sentiment analysis can be integrated into applications to improve communication intent understanding. The example utilizes ngrok to make the local application accessible over the internet and Composer for dependency management, showcasing a straightforward approach to implementing this functionality in a real-world scenario.
