Array Parse_url (string $url)
This function parses a URL and returns an associative array containing the various components that appear in the URL.

$url = ' Http://username:password@hostname/path?arg=value#anchor ';
Print_r (Parse_url ($url));
?>
The example above will output:
Array (Scheme) + HTTP [host] + hostname [user] = username [pass] = password [path] +/path [query] =& Gt Arg=value [Fragment] = anchor)
notes
Note: This function cannot be used for relative URLs.
Note: Parse_url () is specifically used to parse URLs instead of URIs. However, there is an exception to the need for backward compatibility with PHP, which allows three slashes (file:///) for the file://protocol. ）。 No other protocol can do that.
