From: uwendel at mysql dot com Operating system: Linux PHP version: 5.3CVS-2008-02-18 (CVS) PHP Bug Type: PDO related Bug description: Several PDO attributes are documented with the wrong type
Description: ------------ PDO->getAttribute() returns attribute values of different types than described on http://de.php.net/manual/en/ref.pdo.php . PDO::ATTR_CLIENT_VERSION documented : integer actual type returned: string tested with : sqlite, mysql, pgsql suggestion : for BC reasons no change, document it PDO::ATTR_PERSISTENT documented : integer actual type returned : boolean tested with : sqlite, mysql, pgsql suggestion : I have no preference myself PDO::ATTR_SERVER_VERSION documented : integer actual type returned : string tested with : sqlite, mysql, pgsql suggestion : for BC reasons no change, document it PDO::ATTR_STATEMENT_CLASS documented : integer actual type returned : array tested with : sqlite, mysql, pgsql suggestion : update the manual to array I guess it does not matter what driver you use. For example the type setting for PDO::ATTR_PERSISTENT/PDO::ATTR_STATEMENT_CLASS happens in ext/pdo/pdo_dbh.c . However, my point is that the manual and what you actually find differs. Get it in sync and I'm fine.
