parse_url

Synopsis

mixed parse_url(string url)[, int component])

Returns an associative array of the component parts of url. The array contains the following values:

fragment	The named anchor in the URL
host	The host
pass	The user’s password
path	The requested path (which may be a directory or a file)
port	The port to use for the protocol
query	The query information
scheme	The protocol in the URL, such as “http”
user	The user given in the URL

The array will not contain values for components not specified in the URL. For example:

$url = "http://www.oreilly.net/search.php#place?name=php&type=book";
$array = parse_url($url);
print_r($array); // contains values for "scheme", "host", "path", "query",
                 // and "fragment"

If the component option is provided, then just that particular component of the URL will be returned.
