// A URL like http://stackoverflow.com/questions/189113/how-do-i-get-current-page-full-url-in-php-on-a-windows-iis-server:
echo base_url(); // Will produce something like: http://stackoverflow.com/questions/189113/
echo base_url(TRUE); // Will produce something like: http://stackoverflow.com/
echo base_url(TRUE, TRUE); || echo base_url(NULL, TRUE); //Will produce something like: http://stackoverflow.com/questions/
// And finally:
echo base_url(NULL, NULL, TRUE);
// Will produce something like:
// array(3) {
// ["scheme"]=>
// string(4) "http"
// ["host"]=>
// string(12) "stackoverflow.com"
// ["path"]=>
// string(35) "/questions/189113/"
// }
