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 <xref linkend="class.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.
