* Retrieves a modified URL query string.
* You can rebuild the URL and append query variables to the URL query by using this function.
* There are two ways to use this function; either a single key and value, or an associative array.
* Using a single key and value:
* add_query_arg( 'key', 'value', 'http://example.com' );
* Using an associative array:
* ), 'http://example.com' );
* Omitting the URL from either use results in the current URL being used
* (the value of `$_SERVER['REQUEST_URI']`).
* Values are expected to be encoded appropriately with urlencode() or rawurlencode().
* Setting any query variable's value to boolean false removes the key (see remove_query_arg()).
* Important: The return value of add_query_arg() is not escaped by default. Output should be
* late-escaped with esc_url() or similar to help prevent vulnerability to cross-site scripting
* @param string|array $key Either a query variable key, or an associative array of query variables.
* @param string $value Optional. Either a query variable value, or a URL to act upon.
* @param string $url Optional. A URL to act upon.
* @return string New URL query string (unescaped).
