The error is being entered correctly.
You create a string at the beginning of the code:
$data = ...
That is, a string. In the loop you want to add items:
$data[] = ...
Items are added in arrays , not strings.
If it really is to accumulate everything in the same variable ...
... or exchange the beginning for this ...:
$data[] = date('Y-m-d');
... Or adapt in the loop:
$data .= $row-> (aqui você poe o item desejado do objeto retornado);
If this is not the intention, simply rename one of the two variables.
