DESCRIPTION

       Procedural style
       int mysqli_num_rows (mysqli_result  $result)

	Returns the number of rows in the result set.

	The  behaviour	of  mysqli_num_rows(3)	depends  on whether buffered or unbuffered result sets are being used. For unbuffered result sets,
       mysqli_num_rows(3) will not return the correct number of rows until all the rows in the result have been retrieved.

PARAMETERS

	      o $
		result	-Procedural  style  only:   A	result	 set   identifier   returned   by   mysqli_query(3),   mysqli_store_result(3)	or
		mysqli_use_result(3).

RETURN VALUES

	Returns number of rows in the result set.

       Note

	       If the number of rows is greater than PHP_INT_MAX, the number will be returned as a string.

		  exit();
	      }

	      if ($result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name")) {

		  /* determine number of rows result set */
		  $row_cnt = $result->num_rows;

		  printf("Result set has %d rows.
", $row_cnt);

		  /* close result set */
		  $result->close();
	      }

	      /* close connection */

	      ?>

       Example #2

	      }

	      if ($result = mysqli_query($link, "SELECT Code, Name FROM Country ORDER BY Name")) {

		  /* determine number of rows result set */
		  $row_cnt = mysqli_num_rows($result);

		  printf("Result set has %d rows.
", $row_cnt);

		  /* close result set */
		  mysqli_free_result($result);
	      }

	      /* close connection */
