Neocities might be a better option for those that are looking for something like this
But, you can't run PHP on Neocities.
Actually, that applies to any server, (web)hosting, datacenter rack, internet connection, bank account, domain name. As soon as your provider (or the powers that be) notices you, for example a complaint or a government official email, they will take down your hosted system or connection. In 45 year of internet and datacenters I never ever saw an exception to this rule. Even Tor hidden servers are taken down.
