Understanding PHP Documentation Code

Question

I was reading this documentation today and got confused when seeing the output.

The lines of code:

/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf ("%s (%s)\n", $row[0], $row[1]);

/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);

/* associative and numeric array */
$row = $result->fetch_array(MYSQLI_BOTH);
printf ("%s (%s)\n", $row[0], $row["CountryCode"]);

Produces the result:

Kabul (AFG)
Qandahar (AFG)
Herat (AFG)

If there's a combination of loop and data_seek() , then I can understand why the output is different each time. Shouldn't the output from the code above like this?

Kabul (AFG)
Kabul (AFG)
Kabul (AFG)

Am I missing something?

You just had to investigate a little further. The page says that this function "is an extended version of the mysqli_fetch_row()", while by following the link, you'd learn that "Each subsequent call to this function will return the next row within the result set"
