Use a PHP SOAP client to download SMS messages from the M2M Connect server.
Parse all downloaded messages.
Check message metadata (eg name/phone number) against pre-stored values
(preferably stored in a database).
Store the downloaded message (content and metadata) in the database.
Display the message content and metadata on the web-browser
Message metadata: eg source SIM number, name, email address
Message content: ie state of switches on the board, temperature, key-pad value, etc
Send emails reporting the outcome to the user's stored email address (you could also send an SMS).
Looking for this to be done asap.
