[PHP-DB] Number of Lines in Table. SOLVED

Dear List -

This works:

mysql> describe Purchases;
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| indx  | smallint(6) | NO   | PRI | NULL    | auto_increment |
| manf  | varchar(20) | YES  |     | NULL    |                |
| itm   | varchar(50) | YES  |     | NULL    |                |
| prc   | float       | YES  |     | NULL    |                |
+-------+-------------+------+-----+---------+----------------+
4 rows in set (0.00 sec)



  SELECT SQL_CALC_FOUND_ROWS itm FROM Purchases LIMIT 500 OFFSET 0;

+------------------------------------------+
| itm                                      |
+------------------------------------------+

| Fancy Paprika                            |
| Fancy Paprika                            |

| Oregano                                  |
| Oregano                                  |
| Basil                                    |
+------------------------------------------+
453 rows in set (0.00 sec)

mysql> SELECT FOUND_ROWS();
+--------------+
| FOUND_ROWS() |
+--------------+
|          453 |
+--------------+
1 row in set (0.00 sec)

>>>This does not:

$sql26 = "SELECT SQL_CALC_FOUND_ROWS itm FROM Purchases LIMIT 50 OFFSET 0";

/*if (!mysqli_query($cxn, $sql26))
     printf("Errormessage: %s\n", mysqli_error($cxn)); */

$result26 = mysqli_query($cxn, $sql26);
$sql27 = "SELECT FOUND_ROWS()";
/*if (!mysqli_query($cxn, $sql27))
     printf("Errormessage: %s\n", mysqli_error($cxn));*/

$result27 =  mysqli_query($cxn, $sql27);

$row27 = mysqli_fetch_row($result27);
					
print_r($row27);
//output
Array
(
     [0] => 1  //is now the correct value.
)

What is my error?

TIA
