Hi Juanita,
PHP runs on the server-side, but our web servers don't have PHP installed as we use HTML and Javascript.
The PHP samples on Topliners are aimed at our APIs, where the community can use PHP to integrate with our SOAP and REST APIs.
Is there anything specific that you have in mind? We might be able to find a solution without using PHP.
Hope this helps and please let us know if you need more information.
Thanks,
Fred
