Curl Based Plivo PHP Helper Library
A fork of the original open source telephony and SMS framework's Plivo PHP Helper Library (https://github.com/plivo/plivo-php) with slight modifications, to remove dependence on PEAR's HTTP_Request2.
Instead, I opted to go for Curl.
You can use this class with the examples from the original repo: https://github.com/plivo/plivo-examples-php
