get_object_vars() vs. cast to array

Question

Are there any differences between get_object_vars($obj) and (array) $obj ?

Both seem to return the public properties of the object.

Answer 1

The get_object_vars() function is a clearer method of achieving the effect you want. Although casting it to an array is a solution as well, this behavior might change in later versions of PHP.

I don't know if there is an actual difference between the two methods but the arguments above would lead me to use the function.
