Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

PDO class failed to instantiate (connection failed) so you 
don't have a PDO object. Calling methods from a non-object 
results in a fatal error.

Sorry for bad reporting, but non-object is $stmt not $pdo.
If i try:
$pdo = new PDO("mysql:host=localhost;dbname=myDb","myUser","myPass");
$sql = 'select username from users where id = 1';
foreach ($pdo->query($sql) as $row) {
// some code here
}

I not get the problem, so probably the issue is prepare function.
