   mysqli_query($con, "insert into Test values('Kennedy', 27),('Paul', 30),('Justice', 28)");
   print("Table Created.....\n");

   //Reading records
   $stmt = mysqli_prepare($con, "SELECT * FROM Test");

   //Executing the statement
   mysqli_stmt_execute($stmt);

   //Storing the result
   mysqli_stmt_store_result($stmt);

   //Number of rows
   $count = mysqli_stmt_num_rows($stmt);
   print("Number of rows in the table: ".$count."\n");
