How to Use The Number Insight API with PHP

Here is a summary of the text in 1 paragraph: This tutorial demonstrates how to use the Nexmo Number Insights API to validate and gain information about any phone number. To complete this tutorial, you need a Vonage API account with an API key and secret, as well as a virtual phone number. The tutorial uses PHP and Composer dependencies, and provides examples of different levels of service, including Basic, Standard, and Advanced, which offer varying amounts of information about the phone number, such as its type, carrier, roaming status, and reachability. The application uses a SlimPHP framework and displays the form to input the phone number and select the level of insight desired, with the response displayed in a tabular layout. The tutorial also includes handling for errors and provides additional resources for further learning, including API reference documentation, code snippets, and tutorials on other topics such as fraud scoring and phone number verification.
