variant_get_type - Returns the type of a variant object

SYNOPSIS

       int variant_get_type (variant  $variant)

DESCRIPTION

	Returns the type of a variant object.

PARAMETERS

	      o $variant
		- The variant object.

RETURN VALUES

	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.

variant_int - Returns the integer portion of a variant

SYNOPSIS

       mixed variant_int (mixed  $variant)

DESCRIPTION

	Gets the integer portion of a variant.

PARAMETERS

	      o $variant
		- The variant.

       Note

	       As  with  all  the variant arithmetic functions, the parameters for this function can be either a PHP native type (integer, string,
	      floating point, boolean or NULL), or an instance of a COM, VARIANT or DOTNET class. PHP native types will be converted  to  variants
	      using  the  same	rules  as  found  in  the constructor for the "VARIANT" class. COM and DOTNET objects will have the value of their
	      default property taken and used as the variant value.

	       The variant arithmetic functions are wrappers around the similarly named functions in the COM  library;	for  more  information	on
	      these  functions, consult the MSDN library. The PHP functions are named slightly differently; for example variant_add(3) in PHP cor-
	      responds to VarAdd()  in the MSDN documentation.

RETURN VALUES

	If $variant is negative, then the first negative integer greater than or equal to the variant is returned, otherwise returns  the  integer
       portion of the value of $variant.
