/**
* This function parses a URL and returns an associative array containing any
* of the various components of the URL that are present.
* The values of the array elements are not URL decoded.
*
* This function is not meant to validate
* the given URL, it only breaks it up into the above listed parts. Partial
* URLs are also accepted, parse_url tries its best to
* parse them correctly.
*
* @param string $url The URL to parse. Invalid characters are replaced by
* _.
* @param int $component Specify one of PHP_URL_SCHEME,
* PHP_URL_HOST, PHP_URL_PORT,
* PHP_URL_USER, PHP_URL_PASS,
* PHP_URL_PATH, PHP_URL_QUERY
* or PHP_URL_FRAGMENT to retrieve just a specific
* URL component as a string (except when
* PHP_URL_PORT is given, in which case the return
* value will be an integer).
* @return mixed On seriously malformed URLs, parse_url.
*
* If the component parameter is omitted, an
* associative array is returned. At least one element will be
* present within the array. Potential keys within this array are:
*
*
*
* scheme - e.g. http
*
*
*
*
* host
*
*
*
*
* port
*
*
*
*
* user
*
*
*
*
* pass
*
*
*
*
* path
*
*
*
*
* query - after the question mark ?
*
*
*
*
* fragment - after the hashmark #
*
*
*
*
* If the component parameter is specified,
* parse_url returns a string (or an
* integer, in the case of PHP_URL_PORT)
* instead of an array. If the requested component doesn't exist
* within the given URL, NULL will be returned.
* @throws UrlException
