note 21536 added to ref.pgsql

I use postgresql 7.0 et php and I meet a problem with the transaction. For example, with postgres and pgacces only, I begin a transaction which contains 2 requests. I execute only the first one and i don't finish the transaction (no commit). Finally, the transaction is rollback and the request is canceled. When I execute the same with Php, the first request is commit while no commit is executed explicitely. Perhaps, I must open the connection by changing an autocommit mode ? Any idea ? thanks -- http://www.php.net/manual/en/ref.pgsql.php http://master.php.net/manage/user-notes.php?action=edit+21536 http://master.php.net/manage/user-notes.php?action=delete+21536 http://master.php.net/manage/user-notes.php?action=reject+21536
