Mysqli rollback is not working

问题:

I have a MySQL db and I am using mysqli.

for some reason I can't get transactions to work properly. If I call $mysqli->rollback(), it does not roll back.

example code:

$mysqli->autocommit(false);

$sql = "INSERT INTO myTable (name , color) VALUES ('Dan' , 'red')";

$mysqli->query($sql);

$mysqli->rollback();

Tthe result is that another row is added to myTable. Can anyone think of a reason why?
