Warning about globals

carlosruiz

Hi. I configured my php.ini (php 4.3.7) at windows folder for register_globals ON.

I am working with mi application but appeared this warning

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

and i don't know what to do, because is affecting my application. Thanks.

See this page, including the user notes (search for "bug_compat_42").

Do yourself a favor... Turn Register Globals back off and modify your script to function with it off... Running in the on state can be a very dangerous thing, which was why the default option was changed to off several php iterations ago...

Ok. thanks But I have a question. I am working with the same application in a different computer using the same PHP version and this warning message doesn't appear. In both i configure the PHP.INI in the same way and it's not working. What can be the problem. Thanks.

Carlos.

Have you followed the link provided by NogDog? There's some good info in there about that...

Quoted from http://us2.php.net/session

session.bug_compat_warn boolean
PHP versions 4.2.3 and lower have an undocumented feature/bug that allows you to initialize a session variable in the global scope, albeit register_globals is disabled. PHP 4.3.0 and later will warn you, if this feature is used by enabling both session.bug_compat_42 and session.bug_compat_warn.
