In this context the edge is a fancy word to say "serverless". It just means that your PHP interpreter will be started on-demand on a node closer to your customer's request.
So if your website receives no requests, it costs you nothing. And requests have less latency for the user.
That's the theory anyway, in my experience reality is a lot more nuanced because the serverless node still has to reach a database and so on.
