help with explode()

[skdzines]

I am calling a function in the following way from my functions.php page which I'm including using include ('functions.php');

$sql = "Select lastUpdate from revised";
$result = mysql_query($sql);
$revised = mysql_fetch_row($result);
echo "Last Revised: " .format_date($revised)."";

function format_date($revised){
	$date = explode("-", $revised);
	$year = $date[0];
	$month = $date[1];
	$day = $date[2];

switch ($month){
	case "01":
		$month = "January";
		break;
	case "02":
		$month = "February";
		break;
	case "03":
		$month = "March";
		break;
	case "04":
		$month = "April";
		break;
	case "05":
		$month = "May";
		break;
	case "06":
		$month = "June";
		break;
	case "07":
		$month = "July";
		break;
	case "08":
		$month = "August";
		break;
	case "09":
		$month = "September";
		break;
	case "10":
		$month = "October";
		break;
	case "11":
		$month = "Novemeber";
		break;
	case "12":
		$month = "December";
		break;
}

$formatDate = "$month $day, $year";

return $formatDate;
}

The function returns the correct value only if I set $revised inside the function like this:

function format_date($revised){
$revised = "2005-09-11";
	$date = explode("-", $revised);
	$year = $date[0];
	$month = $date[1];
	$day = $date[2];

etc....

if I call it the way I want to in the first example all I get back is this:

Last Revised: , Array

Why?

Any help is appreciated.

Thanks
