I am trying to write a webpage that will present to the public the contents of one of my Google Calendars. The standard iframe doesn't give me the format I'd like and I also want to embed some schema.org event information, update and submit a sitemap, etc.
As I'm fairly experienced with PHP, I'm trying to extract data from the Google Calendar API. I looked at Google's quickstart https://developers.google.com/calendar/quickstart/php but it assumes a level of knowledge I don't possess.
It seems I need to use something called "composer" and tells me I need to do "composer require google/apiclient:^2.0" but I'm unclear where exactly I type this - I can't see anywhere obvious in cPanel - or maybe it goes at the start of my PHP code?
Also, I note that the sample code is command-line only and I can't find code anywhere that would appear to be capable of running as a PHP web page. Is that because it's just not possible?
