使用AWS Elastic Beanstalk上的PHP获取URL中的主机名

Question

Inside a PHP application hosted on Elastic Benstalk I'd like to get and use the host, or domain, part of the url the client used to load the page.

In the past, but on non AWS servers, I have used:

$hostname = $_SERVER[HTTP_HOST];

which would return example.com from a url like http://example.com/index.html. What I'm getting from my code deployed on elastic beanstalk appears to be the ip address of the running instance; it's something like 53.123.123.123.

Is there a way to get the host name - or domain name - of the url that the client web browser requested from my Elastic Beanstalk PHP Application?

Answer 1

You should look in

$_SERVER['SERVER_NAME']

Instead
