PHP getting full server name including port number and protocol

Question

In PHP, is there a reliable and good way of getting these things:

Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080

Answer 1

Why don't you get full url like this

strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['SERVER_NAME'];

or (If you want host name from HTTP)

strtolower(array_shift(explode("/",$_SERVER['SERVER_PROTOCOL'])))."://".$_SERVER['HTTP_HOST'];
