absoluteURI   [line 260]

	

    

    

		string absoluteURI(
string
$url, [string
$protocol = null], [integer
$port = null])
    

    


	
		Absolute URI
This function returns the absolute URI for the partial URL passed.  The current scheme (HTTP/HTTPS), host server, port, current script  location are used if necessary to resolve any relative URLs.
Offsets potentially created by PATH_INFO are taken care of to resolve  relative URLs to the current script.
You can choose a new protocol while resolving the URI.  This is  particularly useful when redirecting a web browser using relative URIs  and to switch from HTTP to HTTPS, or vice-versa, at the same time.








        
Parameters:

    

    

          

        string  
        $url  
        — 
        Absolute or relative URI the redirect should go to.
      

          

        string  
        $protocol  
        — 
        Protocol to use when redirecting URIs.
      

          

        integer  
        $port  
        — 
        A new port number.

		Negotiate Language
Negotiate language with the user's browser through the Accept-Language  HTTP header or the user's host address.  Language codes are generally in  the form "ll" for a language spoken in only one country, or "ll-CC" for a  language spoken in a particular country.  For example, U.S. English is  "en-US", while British English is "en-UK".  Portugese as spoken in  Portugal is "pt-PT", while Brazilian Portugese is "pt-BR".
Quality factors in the Accept-Language: header are supported, e.g.:       Accept-Language: en-UK;q=0.7, en-US;q=0.6, no, dk;q=0.8
