variant_get_type
Returns the type of a variant object
(PHP 5)
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.
