the question is within communication from flex to php 
and i already succeed receiving value at PHP side although I can not
send value as array from php.
(Im able to get value at php side from Database)
How can I send value from php to flex?

P.S. sorry for my terrible English.

$shop_row = $data->get_Data($shop_sql);
 
$return_Data[] = $genre_row;

//I am thinking the error is the way to return the value
echo $return_Data[];

source code of receiving the value
private function get_Result(event:Event):void
        {
                var loader:URLLoader = event.target as URLLoader;
                var result:Array = loader.data;

//I have no idea how to receive the value here.......
