Oracle OCI8 PHP Debian编码错误

Question

i'm despaired of the encoding stuff using a debian 8 server with Instantclient 12.2, php 5.6 and oci8(2.0.12).

I had encoding issues in the php sites itself which i solved by setting the php encoding to ISO-8859-1 in php.ini . -> So encoding, including all european chars, works for php.

Now my problem is that the data I retrieve from our oracle12c database isn't encoded correctly. So i get

a for ä
o for ö
u for ü
? for ß

When saving from php to Database, the same thing happens.

in sqlplus64 client the data is encoded correctly so i guess it has something to do with oci8.

What i tried:

I already set the NLS_LANG parameter to GERMAN_GERMANY.WE8ISO8859P1 and GERMAN_GERMANY.UTF-8 , tried to give oci_connect() a charset manually, tried all encoding options for apache2.conf and php.ini , tried to overwrite eventually loaded configs through .htaccess file and stuff. But none of that worked.

Maybe someone knows a way out?

Answer 1

I solved it with

putenv("NLS_LANG=GERMAN_GERMANY.WE8ISO8859P1");

before oci_connect()

I have absolutely no idea why this is working but I guess the apache can't access the parameters i set via /etc/profile file
