Oracle OCI and characterset issue

Hi there,

I hope that one or another Oracle specialist is on our list, so here's something special for you:

I recently upgraded from Zend Core for Oracle 2.0 to 2.5 (I still use the same php.ini I used with 2.0), and now my database language setup is messed up! All german umlauts are gone and I haven't found a way to get them back.

This is my setup and database connection handling:

1.) I set up the system-wide environment variable:
"NLS_LANG=GERMAN_GERMANY.WE8ISO8859P9"

2.) Additionally, I set up the environment variable within my php script:
putenv("NLS_LANG=GERMAN_GERMANY.WE8ISO8859P9");

3.) Right before executing:
$this->dbh = oci_pconnect($dbUser, $dbPass, "//$dbHost:$dbPort/$dbName", "NLS_LANG=GERMAN_GERMANY.WE8ISO8859P9");

Worked before, but now querying Oracle session language setup ("SELECT * FROM NLS_SESSION_PARAMETERS") returns this:
--------------------------
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR
NLS_DATE_LANGUAGE AMERICAN
NLS_SORT BINARY
NLS_TIME_FORMAT HH.MI.SSXFF AM
NLS_TIMESTAMP_FORMAT YYYY-MM-DD HH24:MI:SS
NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZR
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZR
NLS_DUAL_CURRENCY $
NLS_COMP BINARY
NLS_LENGTH_SEMANTICS BYTE
NLS_NCHAR_CONV_EXCP FALSE
--------------------------

Any ideas and help greatly appreciated!!

Thanks a lot!

Regards, Sascha
