   $con = mysqli_connect("localhost", "root", "password", "test");

   //Executing the multi query
   $query = "SELECT * FROM players;SELECT * FROM emp";
   mysqli_multi_query($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($con)){
         print("::::::::::::::::::::::::::::::\n");
      }
   }while(mysqli_next_result($con));
   mysqli_close($con);
?>

   $res = $con->multi_query("SELECT * FROM players;SELECT * FROM emp");

   do {
      $result = $con->use_result();
      while($row = $result->fetch_row()){
         print("Name: ".$row[0]."\n");
         print("Age: ".$row[1]."\n");
         print("\n");
      }
      if($con->more_results()){
         print("::::::::::::::::::::::::::::::\n");
      }
   } while ($con->next_result());
