Current page's exact URL?
 

How can I get the full and exact URL of the current page? i.e., protocol://server:port/path/filename?argument1=value1&argument2=value2...

I know how to construct it but I thought that there might be a superglobal that already contains this.

in a phpinfo file?

...?

Using PHP, if I used phpinfo I'd already know the page's URL :p

first get root dir with $_SERVER['DOCUMENT_ROOT'] or $DOCUMENT_ROOT, then you can convert it yourself to exact URL. pathinfo() function will help you while you are doing so..

$_SERVER['HTTP_HOST']
$_SERVER['SERVER_PORT']
$_SERVER['REQUEST_URI']

not sure about the protocol an if statement?

if ($_SERVER['SERVER_PORT'] == 443) {
$p = 'https://';
} else {
$p = 'http://';
}
