Ask, PHP in the echo in the row, there seems to be no way to write paragraph name

Excuse me, PHP in the echo in the row, as if there is no way to write paragraph name?
echo " $row [1]";


The above can work properly. If I change to $row->icontext this kind of writing. Will not.

Please expert guidance, thank you.

------Solution--------------------
Of course not!
$row [3] is the contents of the array $row subscript 3
$row->icontext is the Icontext property of the object $row

Although PHP is a weak type, it is not weak to not need to differentiate between arrays and objects
------Solution--------------------
To use the object, use the Fetch_object method.
