Converting PHP Action Files from SOAP API to REST API

Previously we had a Coder create some PHP files that would effectively do a comparison between two database tables and if there was a new or update entry in the persons table, the PHP would go off and either create the record or update it in our Applications tables. This was done using the SOAP API. The SOAP API is now obsolete in our platform and we need someone to take our original code and adapt it or re-write it to give the same functionality using the REST API which is the new API our system allows.

The files we had previously were:
- soapproxy.php
- sync_config.php
- sync_functions.php
-sync_soapproxy.php

API information can be provided as well as copies of the the SOAP existing files on award of the project however i've added an example of the sync_config file in a txt format with random credentials etc.
