PHP 5.1.2 & bundeled PDO

I am trying to return a php_stream object when the user binds a resultset column using PDO::PARAM_LOB. To do so I follow the guidelines stated in the php_pdo_driver.h file:

/* get_col: when len is 0 ptr should point to a php_stream *,
 * otherwise it should behave like a string. Indicate a NULL field
 * value by setting the ptr to NULL */

I set the length as 0 and return the php_stream*.
However PDO/PHP recognizes this as String(0)"" instead of a php stream.
