Multi-array - What am I missing?

["Chris Ditty" <cditty@xxxxxxxxx>]

Can anyone point me in the right direction?  I know I am missing something
simple, but I can't place my hands on it.

$myCalTime = act_getCalendarDays($config, $myMonth, $myYear);

foreach($myCalTime as $calTime => $calArrayTime){
    $calArray[] = $calArrayTime['day']."=>array('NULL','linked-day
".strtolower($calArrayTime['reason'])."','".$calArrayTime['day']."'),";
}

act_getCalendarDays returns this....
Array
(
    [day] => Array
        (
            [0] => 05
            [1] => 06
            [2] => 26
            [3] => 27
        )

    [reason] => Array
        (
            [0] => Vacation
            [1] => Vacation
            [2] => Vacation
            [3] => Vacation
        )

)


What am I missing to get this
=>array('NULL=','linked-day ',''),

to look like this
05=>array(NULL,'linked-day vacation','05'),
