&reftitle.intro;
The VARIANT is COM's equivalent of the PHP zval; it is a structure that
can contain a value with a range of different possible types. The variant
class provided by the COM extension allows you to have more control over
the way that PHP passes values to and from COM.

When returning
a value or fetching a variant property, the variant is converted to a PHP
value only when there is a direct mapping between the types that would
not result in a loss of information. In all other cases, the result is
returned as an instance of the variant class. You can force PHP to
convert or evaluate the variant as a PHP native type by using a casting
operator explicitly, or implicitly casting to a string by
printing it. You may use the wide range of variant
functions to perform arithmetic operations on variants without forcing a
conversion or risking a loss of data.
