Change all values in dataframe to NA or 0

How do I change all values in a dataset to NA or 0, while preserving all column names and ideally, preserving an identical data structure.

We can just do assignment while using [] to preserve the attributes

df1[] <- 0

Or for NA

df1[] <- NA

-testing

> df1 <- head(iris, 3)
> df1[] <- 0
> df1
  Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1            0           0            0           0       0
2            0           0            0           0       0
3            0           0            0           0       0
