[wp-hackers] WP/PHP Syntax Question...

[Brian Layman]

I'm just making sure I'm not missing something in the PHP syntax....

In Classes.php, WP_Query::get_date_permastruct is declared like this
(without any parameters specified):	

function get_date_permastruct() {
[...]
}


In the functions get_year_permastruct() and get_month_permastruct(), it
is called with a parameter like this:
$structure = $this->get_date_permastruct($this->permalink_structure);

Since there is no parameter declared in get_date_permastruct, I'm making
the assumption that this value is ignored.  I just wanted to make
certain that this wasn't PHP syntax for a default value if a return
false or return 0 is called.  That would be a pretty obscure way of
doing default values, but with the rest of this WP code being fairly
clean, its almost surprising to see something wrong.

Am I guessing right that this is just legacy code or something to that
effect and PHP just ignores extra parameters being passed to a function?
Or is there something else going on of which I am unaware?
