VARIANT_AND(3)								 1							    VARIANT_AND(3)

variant_and - Performs a bitwise AND operation between two variants

SYNOPSIS

       mixed variant_and (mixed  $left, mixed  $right)

DESCRIPTION

	Performs a bitwise AND operation. Note that this is slightly different from a regular AND operation.

PARAMETERS

	      o $left
		- The left operand.

	      o $right
		- The right operand.

       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.
