Queue Management PHP or Java Script

I would like a php or java script that would create a virtual token queue monitor with alerts sent SMS through Twilio. A user would enter their phone number, then receive a token number, see number of how many in front of them, and what token number is currently being served. Similar to that of a restaurant or deli. Since Twilio has API access, I would like to implement a text SMS message to remind the user their token is next in queue. A webpage on our server that shows the information such as current token number and next 5 tokens in line. A basic css style script is fine that I can edit for appearance of the monitoring page. Thank you for your interest. If this could be done with mac AppleScript, that is your preference, that is fine as well.
