Description:
------------
For about a week ago I had installed on my box Apache 2.2.10 with PHP 
5.2.7. Beside this the php was compiled with FirebirdSql and Oracle 
Instant Client.

On apache start I put a env variabile
export NLS_DATE_FORMAT=DD.MM.YYYY

On my application start point from PHP I also double ensure the 
NLS_DATE_FORMAT it's set so I put also
putenv('NLS_DATE_FORMAT=DD.MM.YYYY');

Everything was ok and my application display the date format from 
oracle as I set it. All good.

Last week ... I made upgrade to Apache 2.2.11 and PHP 5.28.
After upgrade nothing change to my application or configuration only 
this applications (apacheand and php) as I mentioned above.

From this point the date format that I was getting from Oracle was 
NOT what I set.
The returned date format was in Oracle standard DD-M-RR.

So I try everything .. recheck ... reset env variables .. put extra 
configuration for php ... but no result. The same bad date.

I know I could use the alter session as a work-arround ... but this 
envolves running the alter session eache time user wants information 
from the database. The application it's huge and with a lot of users 
and it's running on the intranet system. 
So I preffer the PUTENV method.

So all was ok until the upgrade from apache 2.2.10 to 2.2.11 and php 
5.2.7 to 5.2.8








Reproduce code:
---------------
I try all this ... at once and one by one ... no result.

$_ENV["NLS_DATE_FORMAT"]  = 'DD.MM.YYYY';
putenv('NLS_DATE_FORMAT=DD.MM.YYYY');
apache_setenv('NLS_DATE_FORMAT=DD.MM.YYYY');

Expected result:
----------------
The Oracle date format to be:

22.01.2009

Actual result:
--------------
22-JAN-09
