Always return JSON from your PHP. Then you can include as many variables as you need in your response, and an error code as well if appropriate - like this:\
{"error":"0","result1":"result 1 data","result2":"result 2 data"}Then your success function can become:\
success: function(data) { if (data.error != 0) { // An error occurred on server: do something } else { $("#sku").val(data.result1); // do something with data.result2 }},Your PHP would become something like this:\
if(isset($_REQUEST['ddl1'])) { echo json_encode(array("error"=>0, "result1"=>"FOUND1"));}else{ json_encode(array("error"=>1, "result1"=>"NotFOUND"));}
