PDO assigns values directly to properties using the column name as the property name, and if the property does not exist, create a dynamic one. By default, PDO will assign the properties prior to calling the constructor with the provided constructor arguments. Using PDO::FETCH_PROPS_LATE the order is flipped, the constructor is called first with the provided arguments, and then PDO populates the properties. What the constructor does with the constructor arguments is up to the constructor. If it overwrites a property / set a default value then yes this can overwrite values from the DB. But this issue already exists with positional arguments. And the constructor could do something completely different with the provided arguments that do not interfere at all with values coming from the DB. Hope this clarifies the behaviour.
