?>

but 1 record come please me

your problem each time foreach executes, overrides content of $json variable. try declaring $json first , using it.

if($record) {     $json = array();     foreach($record $rec)     {         $json[] = array("msg"=>$rec);         //   /\ means adding attribution end of array.     } } 

this way, each time foreach executed, content of $json won't replaced, instead appended.
