I want to use PHP 7 when it comes out, but my server admin refuses to upgrade past PHP 5.3.3 and I don't have root privileges. I can run a webserver on port 1024 or higher, but I need it to be available on ports 80 and 443.
I am considering connecting to this userland webserver via a local SOCKS client in PHP. Can I effectively run a PHP 7 webserver on port 80 and 443 this way, and will it be possible to handle PHP requests and sessions correctly?
No. Port 80 is a privileged port.
