Constructs a new variant object.

value: Initial value. If omitted, or set to null an VT_EMPTY object is created.
type: Specifies the content type of the variant object. Possible values are one of the VT_XXX 预定义常量. PHP can detect parameters passed by reference automatically; they do not even need to be passed as variant objects. Consult the MSDN library for additional information on the VARIANT type.
