Why might PDO (php 5.3) not throw errors?

Question

PHP

The basis correctly writes if the correct request. If the request is in error, both
errorCode() and errorInfo() return zeros (same as with correct notation):
Array
(
[0] => 00000
)
Where to look? Is it possible to fix without getting into the ini file of the server?
