$ SERVER变量和double localhost

Question

I've built a function that basically links an excerpt to its relative post. In order to do that I have figured that the variable $_SERVER['SERVER_NAME'] could come in handy in building the path.

I don't know if this is due to the fact I am testing the page on a local environment, but on my local machine the path I have is like http://localhost/webdir/localhost/index.php?p=3 localhost is repeated twice. What could possibly cause this?

Answer 1

use like this

$link='http://'.$SERVER_['SERVER_NAME'];

And if you don't want any GET type of value use this

$l1=explode('?',$SERVER_['SERVER_NAME']);
$link='http://'.$l1[0];

Hope this help you.
