POO list records

Question

Hey, guys, which of these ways is best to list the bank records? The first is the structured way and the second is the object oriented is not? Thanks.

First:

$sql = $usuario -> listar();

foreach($sql AS $registro)
{
    echo $registro['nome'];
}

According to:

$sql = $usuario -> listar();

foreach($sql AS $registro)
{
    $usuario -> setNome($registro['nome']);
    echo $usuario -> getNome();
}
