Description
int 
variant_get_type ( variant variant )
    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.
   
    In PHP versions prior to 5, you could obtain this information from
    instances of the VARIANT class ONLY, by reading a fake
    type property.  See the VARIANT class for more information on
    this.
