JavaScript - var = [

Hola de nuevo, tengo esta funcion:

<script type="text/javascript">

var SPECIAL_DAYS2 = [[2008, 06, 18],
[2008, 07, 03],
[2008, 07, 12],
];

function dateIsSpecial2(year, month, day) {
for (ii = 0; ii < SPECIAL_DAYS2.length; ii++) {
if (((SPECIAL_DAYS2[ii] [0]) == year) &&
((SPECIAL_DAYS2[ii] [1]) == month) &&
(((SPECIAL_DAYS2[ii] [2]) == day))) {
return true;
}
}
return false;
};

Y quiero sustituir el valor de "var SPECIAL_DAYS2 " por un valor que recojo de aqui:

$query = "select arrival from confirmed where room_id = 1";

$result = mysql_query($query);

while ($row = mysql_fetch_assoc($result)) {
list( $anio, $mes, $dia ) = explode( "-", $row['arrival'] );

Si listamos echo "[$anio, $mes, $dia], "; tendremos esto:

[2008, 06, 18]
[2008, 07, 03]
[2008, 07, 12]

y eston son los valores que quiero darle a "var SPECIAL_DAYS2 ", osea:

var SPECIAL_DAYS2 = list( $anio, $mes, $dia ) = explode( "-", $row['arrival'] ); ??

Gracias de antemano.
