Ah, I see now. Well, to answer your first question, it won't work. The
type of $MyVar->getArray is function (or callback), not array.

The proper way of writing a getter in PHP is like so:

<?php
class myClass {
    private $_array = array();

    public function __get($name) {
        switch ($name) {
        case 'array':
            break;
        }
    }
}
?>

In this example, when you fetch "$MyVar->array" you will get the array
by value and not by reference, so the following code will work...

<?php
$MyVar = new myClass();
$mydate = $MyVar->array[1];
?>

...but the following code won't...

<?php
$MyVar = new myClass();
$mydate = 'Mon';
$MyVar->array[1] = $mydate;
?>

...because the property $_array will never be manipulated.

Do you want to be able to manipulate the array in the object, or just
return the array?
