Operating system: windows 2000 iis 5
PHP version: 4.3.3
PHP Bug Type: Session related
Bug description: Random "cannot change the session's ini settings" errors
Description:
------------
I am recently upgraded to php 4.3.3 from 4.2.9 and am using the
php4isapi.dll on iis. My application has been working w/o any problems for
quite awhile and after the upgrade, without rhyme or reason I am getting
the following error every few days:
PHP Warning: Unknown(): A session is active. You cannot change the
session module's ini settings at this time. in Unknown on line 0
I have no ini_set statement in my application and have even set my php.ini
to read only in the event that it was somehow being modified. My
application is EXTREMELY simple... it's basically just consists of a few
html forms submitting to a sql db. Authentication happens via IIS and I'm
using $AUTH_USER to get the user id.
Since this error is extremely intermittent and only happens 2 or 3 times a
week, I cant seem to figure out what line seems or even what function is
causing this error. I know that bugs cannot be solved w/o a code example
that generates the error but I canAll I know is that the version of PHP is
all that's changed so I'm inclined to think it's a bug.
Php.ini is set up as follows:
session.save_handler = files
session.save_path = C:\PHP\sessiondata ; argument passed to
save_handler
session.use_cookies = 1
session.name = PHPSESSID
session.auto_start = 0
session.cookie_lifetime = 0
session.cookie_path = /
session.cookie_domain =
session.serialize_handler = php
session.gc_probability = 1
session.gc_maxlifetime = 50400
session.referer_check =
session.entropy_length =
session.entropy_file =
;session.entropy_length = 16
;session.entropy_file = /dev/urandom
session.cache_limiter =
;session.cache_limiter = nocache
session.cache_expire = 180
session.use_trans_sid = 1
Reproduce code:
---------------
As stated above, I'm really not sure WHAT is causing this error. No
filename is mentioned in the error. My login.php included in every page is
pretty simple:
session_start();
if(!isset($logged_in) || $logged_in != "!authenticated!") {
header("Location: http://myurl.com";);
exit;
} else {
$user_id= str_replace("windows_domain\\\\", "", strtolower($AUTH_USER));
}
Actual result:
--------------
Generic 500 error page in IE for the user... On one occasion when this
happened I had to restart IIS before PHP would work again....
