The values for the attributes above are all defined in terms of the Zend
API. The Zend API contains macros that can be used to convert a *zval to a
value. These macros are defined in the Zend header file, zend_API.h in the
Zend directory of your PHP build directory. Some of these attributes can be
used with the statement attribute handlers such as the PDO_ATTR_CURSOR and
PDO_ATTR_CURSOR_NAME. See the statement attribute handling functions for
more information.
