TUI Calendar customization

I am trying to build a booking calendar using TOAST TUI Calndar. On the link below [login to view URL] is using [login to view URL] to generate random data to populate the calendar. I need someone to modify the [login to view URL] so that data is pulled from the MySQL database using PHP. [login to view URL] Also when while navigating into the calendar (going forward or backward calendar should fetch data from the database and populate based on whichever month you navigate to.
