Updates on PHP Website

We already have a working WebRTC app ( [login to view URL] ) on our website which records audio and have option to save on the server. Now want to make few changes as follows 1)- You will implement it in teacher's account audio recording will start by clicking 'Activate' button ( [login to view URL] ) from Teacher's account and end by clicking on 'End button'. 2)- There will be 'Audio option' only (will be hidden), and other options will be removed like Video and screen sharing, play back [login to view URL] . 3)- Currently it's uploading recordings on 'upload' folder. Now, recordings will be saved in each teacher's own folder. 4)- Currently, it's giving file name in digits, Now, we want to give files name according to current time an date. 5)- Recordings will be deleted after few days from each teacher's folder.
