You can throw it into lambda or vercel for that matter too. Yes you can use sketchy hosts but still can use legit ones too to host for free or very little money.

You can throw basically anything on lambda. That’s hardly a feature of php

Might be useful for teenagers / people with no disposable income to start trying web related stuff from a public library.

Maybe? That’s still not a super great selling point for a language.

When I was a teenager I used to host sites on an old android tablet. These days if you have a credit card, you can make use of the free plans most platforms have and free credit, especially if you have an .edu email.
