new schedule page based on json data instead of database back-end - ChatGPT for Javascript to PHP translation

Initially created a Google apps script / Google Sheet version to replicate the schedule page and audio search page -

Then created a php-based version to run on our local server, since remote server audio search functionality was being dropped in favour of SSSMC search page -

Tried using ChatGPT to convert code snippets from Javascript to PHP. It was surprisingly good. Saves a lot of time.
