Consume Msg and return to another class

[Ruben]

Hello Now my callback function can make a print(echo or print) of the response of the server, but i want return this value, outside of Callback function like this 

$msg_answer="";
function process_message($msg){
 echo $msg->body; //this print a object
        $msg_answer=$msg->body;
       


          return $msg->body;
 
 };
$ch->basic_consume($queue_name, 'sportbetperu-Consumer', false, false, false, false, 'process_message');



//close
//close


return msg_answer or process_message//  i try with $callback = function($msg)..... and try return $callback, but that is null
