SMPP Client with PHP

We already have a website that has parameters to connect with sms gateways. This works well on our desktop version of this same task we are engaging for. We require a php coder to work on an SMPP class and a test page. The SMPP test page must be able to connect to an SMPP server on designated port. The web page must be able to send web sms. Functions: Version: SMPP version 3.x to 3.4 send single message; large messages are automatically split send message to multiple recipients at once Request and save delivery reports to database Schedule messages for future sending must have support for XML. Beginners should please NOT apply. Similar work experience on SMPP is an added advantage.
