variant_mul
(PHP 5, PHP 7, PHP 8)
variant_mul — Multiplies the values of the two variants
Parameters
-
left -
The left operand.
-
right -
The right operand.
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() in PHP corresponds to
VarAdd()in the MSDN documentation.

| Either expression is NULL | NULL is returned |
| Both expressions are empty | Empty string is returned |
