VARIANT_MUL(3)								 1							    VARIANT_MUL(3)

variant_mul - Multiplies the values of the two variants

SYNOPSIS

       mixed variant_mul (mixed  $left, mixed  $right)

DESCRIPTION

	Multiplies $left by $right.

PARAMETERS

	      o $left
		- The left operand.

	      o $right
		- The right operand.

	Boolean values are converted to -1 for FALSE and 0 for TRUE.

       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.

variant_cmp - Compares two variants

SYNOPSIS

       int variant_cmp (mixed  $left, mixed  $right, [int  $lcid], [int  $flags])

DESCRIPTION

	Compares $left with $right.

	This function will only compare scalar values, not arrays or variant records.

PARAMETERS

	      o $left
		- The left operand.

	      o $right
		- The right operand.

	      o $lcid
		- A valid Locale Identifier to use when comparing strings (this affects string collation).

	      o $flags
		-$flags can be one or more of the following values OR'd together, and affects string comparisons:
