Make Phone Calls Using PHP and Twilio Programmable Voice

To make a phone call using PHP and Twilio Programmable Voice, you need to create an environment with the required dependencies installed, set up your Twilio credentials, and write a code that uses the Twilio PHP Helper Library to interact with Twilio's REST APIs. The code creates a new TwiML Bin, which is a publicly accessible URL with the TwiML call instructions, and then makes a phone call using the `twilio->calls->create()` method, passing in the recipient's phone number, the Twilio phone number, and the publicly accessible URL with the TwiML call instructions. The code prints the call's SID to the terminal after a successful call is made, allowing you to test the functionality of the code.
