(PHP 5, PHP 7, PHP 8)
variant_get_type — Returns the type of a variant object
variant
The variant object.
This function returns an integer value that indicates the type of
variant
, which can be an instance of
com, dotnet or
variant classes. The return value can be compared
to one of the VT_XXX
constants.
The return value for COM and DOTNET objects will usually be
VT_DISPATCH
; the only reason this function works for
those classes is because COM and DOTNET are descendants of VARIANT.
