Description:
------------
In PHP 4.4.2 and 4.4.3 (cannot test earlier ones any more), the option session.use_trans_sid cannot be changed by function ini_set, but can be changed using php.ini or the command-line option -d. Also ini_set always returns 0 as the old value for session.use_trans_sid, even if it was set to 1. (BTW, this causes test ext/session/tests/bug36459.phpt to fail -- not because of bug 36459, of course.)
The bug persists even on a second call to ini_set (unlike bug #30422).
Configuration:
env CC=/opt/SUNWspro/bin/cc CFLAGS=-xO2 \
./configure  --enable-discard-path --enable-force-cgi-redirect --with-ndbm --with-dba --with-db --with-db2=/opt/dpiwww/apache --with-mysql=/opt/dpiwww/mysql --enable-sysvsem --enable-sysvshm --with-exec-dir=/opt/dpiwww/php/bin --with-config-file-path=/opt/dpiwww/php/lib --prefix=/opt/dpiwww/php --disable-debug --with-zlib --with-bz2 --with-gd --with-jpeg-dir=/usr/sfw --with-png-dir=/usr/sfw --with-xpm-dir=/usr/openwin --with-freetype-dir=/usr/sfw --enable-gd-native-ttf


Reproduce code:
---------------
*** Script 1:
<?php
printf("%d\n",ini_get('session.use_trans_sid'));
printf("%d\n",ini_set('session.use_trans_sid',1));
printf("%d\n",ini_get('session.use_trans_sid'));

*** Script 2:
<?php
printf("%d\n",ini_get('session.use_trans_sid'));
printf("%d\n",ini_set('session.use_trans_sid',1));
printf("%d\n",ini_get('session.use_trans_sid'));

Expected result:
----------------
*** Script 1:
If previously 0:
0
0
1
If previously 1:
1
1
1

*** Script 2:
If previously 0:
0
0
0
If previously 1:
1
1
0

Actual result:
--------------
*** Both Scripts:
If previously 0:
0
0
0
If previously 1:
1
