Php Url Detection?

[azrag]

hey guys im curious if there is a function in php that allows it to detect what the current url is that the user is on. For example if the browser says your on http://newgrounds.com/tomnaked.php can php echo that url and if so how?

[Afro-Ninja]

$url = 'http';
if($_SERVER['HTTPS']=='on')$url .= 's';
$url .= '://';
$url .= $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
echo $url;

the url starts with http, then adds an s if 'https' is on (secure socket)
then it adds :// regardless. http_host retrieves your site url, then request_uri gets the rest for you, including the query string if there is one.

if you want the query string separate you can use PHP_SELF for just the file name, and QUERY_STRING for the.. query string
