Problème fonction et coordonnées BDD

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

\\\\\\\\\\ma tentative de code qui ne fonctionne pas :
function coor($cod){

          $conn = db_connect();
		if(!$conn)
			return false;

          $sql1 = "SELECT lat FROM maps_ville WHERE cp='$cod'";
          $sql2 = "SELECT lon FROM maps_ville WHERE cp='$cod'";
          
          $query1 = @mysql_query($sql1);
          $query2 = @mysql_query($sql2);

		if( @mysql_num_rows($query1) == 0 )
			return false;
			
		if( @mysql_num_rows($query2) == 0 )
			return false;

		$result1 = result_to_array($query1);
		return $result1;
		
		$result2 = result_to_array($query2);
		return $result2;
	}



/////////Code google qui fonctionne, j'ai changé les coordonées en $result1, $result2  ligne 4:

function initialize($coor){


     var centreCarte = new google.maps.LatLng($result1, $result2);
     var optionsCarte = {
          zoom: 8,
          center: centreCarte,
          mapTypeId: google.maps.MapTypeId.ROADMAP
     }
     var maCarte = new google.maps.Map(document.getElementById("EmplacementDeMaCarte"), optionsCarte);
}
</script>
