   $query = "SELECT * FROM players;SELECT * FROM emp";
   mysqli_multi_query($con, $query);

   do{
      $result = mysqli_use_result($con);
      while($row = mysqli_fetch_row($result)){
         print("Name: ".$row[0]."\n");
         print("Age: ".$row[1]."\n");
         print("\n");
      }
      if(mysqli_more_results($con)){
         print("::::::::::::::::::::::::::::::\n");
      }
