I've had a bit of a problem with a function I'm using for a form.
Essentially, the function looks like this:

function addEvent($values = Array('name' => '', 'venue' => '',
'description' => '', 'errors' => Array()))
    // code here displays the form

The function is used to both display an empty form, and the form
populated with values again should there be any validation errors.

Now this works fine when the form has been filled out and there are
errors present, as I can call the function with the correct array
values. However, when I call the function with no arguments (intending
the function to populate the $values array itself) all it does is
present me with an empty array. A print_r($values) just returns
Array( ), no key values defined.

I altered the function to this:

function addEvent($values = Array())
    if(count($values) == 0)
        $values = Array('name' => '', 'venue' => '', 'description' =>
'', 'errors' => Array());
    // code here displays the form

then all works as intended. Question is, am I being dense, or is there a
reason why this shouldn't work?
