Hi there, I keep getting this error in my logile

[17-Mar-2003 11:20:36] PHP Warning:  Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0


I have register_globals off and have tried settting

session.bug_compat_42 = 1 (and On)
session.bug_compat_warn = 0 (and Off)

but it still comes up in my logfiles, it seems to be ignoring whatever I put in php.ini and I have restarted Apaache to make sure it rereads the ini

There was another report about this, and it was solved
by upgrading to the latest stable snapshot from http://snaps.php.net/

Also make sure the php.ini is actually used by PHP.
(check the phpinfo() output)

I have now upgraded to latest stable release but afraid to say that these settings are still ignored and i'm still getting the following error message with no line number or file assocaited with it.

Then you are editing the wrong php.ini file or perhaps not actually running 4.3.  Check phpinfo() to see which version it is and where it is expecting to read your php.ini file from.

Hi there,

I already checked and there's only 1 PHP.INI on my system and I am running latest version here's phnfo output showing version & ini path

PHP Version 4.3.2-RC 

System  Windows NT NUSWEB1 5.0 build 2195  
Build Date  Mar 17 2003 10:15:18  
Server API  Apache  
Virtual Directory Support  enabled  
Configuration File (php.ini) Path  C:\WINNT\php.ini
 [2003-03-17 19:51 UTC] sniper@php.net 
And your php.ini is under C:\winnt\ ??

I have same problem here and it give me a headeach because it involve my client website.

Someone can advise some solutions?

The problem normally arises when you are using a SESSION variable and a standard variable with the same name

i.e $_SESSION['amount'] and $amount

one possible fix (untested) is to kill the session if you have finished with it or unset your variables

I beleive you can also issue an ini_set call to fix this but most of the time I have fixed this by just renaming variables

Regardless of the SESSION problem, the error message cannot be turned off in php.ini with :

session.bug_compat_42 = 1 
session.bug_compat_warn = 0 

neither with what is suggested in the error message :

session.bug_compat_42 = off
session.bug_compat_warn = off

tested with PHP Version 5.2.5
