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.
