php - Transfer constants between url include files -


i have index.php 

define ('server_root', '/foo'); define ('site_root', 'http://localhost'); include (site_root . server_root . '/config.php');

in config.php 

echo site_root;

returns null.

the reason if include http:// localhost , not localhost, constants not passed. can't set site_root localhost.. nothing happen

what's proper systematical solution issue?
