You can not use while using PDO, you can use it using procedural approach.

Some reference: REFERENCE LINK

You can use $db->exec for insert & update query. Not when you want to fetch the records.

Try the following changes.

$db = new PDO('sqlite:db/logs');
//connection code here
$result = $db->query("SELECT * FROM users"); //replace exec with query

foreach($result as $row){
    $row['field1'];
    $row['field2'];
}
