Get the url of page via PHP

Hello,

I want to save the url of a page in a variable so that I can use it later.
There are many pages I want to do that to so writing it manually everytime like this: $variable="http://www.foo.com/foo1.html"; isn't an option.

There has to be a php function that can get the url from the browser, right? I'd appreciate some help.

 

$uri = 
	'http' . (!empty($_SERVER['HTTPS']) ? 's' : null) . '://' .
	$_SERVER['HTTP_HOST'] .
	($_SERVER['SERVER_PORT'] != 80 ? ":{$_SERVER['SERVER_PORT']}" : null) .
	$_SERVER['REQUEST_URI'];
	
echo $uri;

PHP:

 

Thanks. Much appreciated.

 

Note that the code above takes care of https connections and other ports than the default. In most cases something like this is enough:

$uri = "http://{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";
