<?php
$sql = 'select * from price';
$dbh = new PDO('firebird:dbname=localhost:d:\interbasedata\test.fdb;charset=win1251', 'sysdba', 'masterkey');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sth = $dbh->prepare($sql);
$sth->execute();
$obj = $sth->fetch();
var_dump($obj);
$sth = null;

only 1 dialect

Also affected on macosx using PHP 5.3.10 and debian lenny with PHP 5.2.6-1+lenny16.

Something odd: incorrect results are the same for a column for all rows fetched:
using the previous example:

public 'COST' => string '1.00' <-- Error

All rows fetched will have 'COST' set to '1.00' (even if actual values differs)


Running again the query will give another (eg: '600.000000') incorrect value, the same on all rows again.

Currently it is possible to create databases in Dialect 1 and 3 only, however it 
is recommended that you use Dialect 3 exclusively, since Dialect 1 will 
eventually be deprecated.

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

Please use dialect 3 that is the default dialect for firebird 2.5 
Dialect 1 will be deprecated

dialect 1 returning SQL_DOUBLE with var->sqlscale < 0
with quick and dirty patch ignoring var->sqlscale for SQL_DOUBLE, it works but returns not so pretty double numbers (with six digits after comma, like 123.450000 istead of 123.45)
