PHP display server IP Address

Question

I\'m working on a website, and one of the things I would like to do is display MY IP address to users. The website is made with CodeIgniter, so I was looking to find my server

Answer 1

Try $_SERVER['SERVER_ADDR']. It will be the IP address that the server is listening on. You can use DNS functions (e.g., gethostbyaddr()) to get the host name.
