Creating a Phone Status Checker with Nexmo and PHP

The text discusses creating an application using PHP and Nexmo's Voice API to automate tasks such as calling and sending SMS messages. The author shares their personal experience working in a web agency where distractions were common, leading them to design a solution to improve workflow efficiency. They outline the steps to set up a Voice Application on the Nexmo dashboard, including generating an application name, event URL, public/private key pair, and API credentials. The text then delves into implementing the Nexmo client in PHP, creating a reusable service class, and adding functionality to send SMS messages using the Nexmo messaging API or its existing client. Finally, the author shares their completed example code, which includes a controller that reacts to event webhooks sent by Nexmo after every call, echoing an alert if the call fails. The goal is to create a simple phone status checker that can be expanded upon in various ways.
