OCI-Lob->load returns broken character or nothing in php 5.2.0RC4.
It is occurred in 64bit linux, in 32bit linux OCI-Lob->read returns correct multibyte string.

My Oracle database is R10., charset is AL32UTF8.

Downgrading to php 5.2.0RC1, it works correct, so this might be bug.

Best regards
Hideaki Masui

Reproduce code:
$conn = oci_connect('scot', 'tiger', 'xxx');
if (!$conn) exit;


$stid = oci_parse($conn, $query);
if (!$stid) exit;

$r = oci_execute($stid, OCI_DEFAULT);
if (!$r)  exit;

while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS)) {

  echo $row['LOBDATA']->load() ."\n";



Expected result:
The "echo $row['LOBDATA']->load();" line should return
the actual mulitibyte string from the select statement.

Actual result:
$row['LOBDATA']->load() returns broken character or nothing.

Cannot reproduce.
Make sure your NLS_LANG is set and equals to something similar to ".AL32UTF8".
 [2006-09-27 09:56 UTC] masui at emplex dot co dot jp
Yes, I set ".AL32UTF8" to NLS_LANG.

My CLOB data in Oracle is "?Z?????O?l?ܘZ??????".

Broken is only 64bit Linux only, 32bit linx is ok.
 [2006-09-27 10:04 UTC]
How did you set NLS_LANG? How do you test it?

>Broken is only 64bit Linux only, 32bit linx is ok.
I'm testing on 64bit host and it works perfectly fine with Oracle10g/UTF8.
 [2006-09-27 10:53 UTC] masui at emplex dot co dot jp
I set NLS_LANG in /usr/local/apache2/bin/envvars.

Following is my setting.
export ORACLE_BASE=/home/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export NLS_LANG=.AL32UTF8
export ORA_NLS10=$ORACLE_HOME/nls/data

I tested by access from web browser.

Following is create table and insert data.
 [2006-09-27 11:00 UTC]
Just insert plain Unicode data and select it from the table.
 [2006-09-27 11:01 UTC]
This is what I get back when I insert UTL_RAW.CAST_TO_VARCHAR2('A3B0A3B1A3B2A3B3A3B4A3B5A3B6A3B7A3B8A3B9'):

string(40) "�Zˆ?“?ŽOŽlŒ?˜ZŽ?”?‹?"

 [2006-09-27 11:02 UTC]
...which is exactly what you posted earlier:
"My CLOB data in Oracle is "�Zˆ?“?ŽOŽlŒ?˜ZŽ?”?‹?"."
 [2006-09-27 11:15 UTC] masui at emplex dot co dot jp
Yes, your CLOB DATA is correct.

I tested for Japanease UTF-8.
 [2006-09-27 11:25 UTC]
So, what's the problem then?
 [2006-09-27 11:31 UTC] masui at emplex dot co dot jp
Can your CLOB data be returned by reproduce code correct?
 [2006-09-27 11:40 UTC]
Yes, with your code I get valid Unicode data I inserted before.
Please try to run it in console (but don't forget to set NLS_LANG first).
 [2006-09-27 12:11 UTC] masui at emplex dot co dot jp
Following is my php configure option. Is it correct?

./configure \
--with-apxs2=/usr/local/apache2/bin/apxs \
--enable-mbstring \
--enable-mbregex \
--with-zlib \
--with-curl \
--with-dom \
--with-dom-xslt \
--with-openssl \
--enable-sigchild \
--with-oci8=/home/oracle/product/10.2.0/db_1 \
 [2006-09-27 12:20 UTC]
I don't see any problems, though I would test it with --disable-all --with-oci8=<...> instead.
