How to turn my opencv python project into web service?

My project is face expression recognition, using opencv and Support Vector Machine. My code's in python 3.x I'm looking for the way to create a web service for my project. But i didn't have any experience with PHP neither web working. I want to detect face in web browser though my camera using opencv, then send that face image to my back-end to recognize its emotion. Any idea how can i do it?? Thanks!
