 Has anyone encountered this warning?

 Warning: Unknown: Your script possibly relies on a session side-effect

 warning by setting session.bug_compat_42 or session.bug_compat_warn to
 off, respectively in Unknown on line 0

 I seem to remember this happening before, but I don't remember the
 solution. As I remember, it wasn't really reporting an error, but
 something else. I just don't remember how I dealt with it before.

 I don't know how to set session.bug_compat_warn to off.

 Any ideas?



 PS: I'm using php 5.2.10 and register_global is OFF.

This will reproduce the error:

$_SESSION['test'] = null;
$test = 1;

It has something to do with using a global var that is the same name as
a session var, but the session var has to be null it seems.


That's it! I remember now. I knew it was something simple and really stupid.

As it turns out, the problem here is that this error is NOT consistent. Most of the time you don't need to worry about what you name your variables and session variables. But every once in a while if you are in the habit of naming variables the same name as session variable (as I do), then the practice sometimes generates an error.

So to solve the above problem, all you have to do is use a different variable name than the session name for that instance -- something like:

$_SESSION['session_test'] = null;
$test = 1;

But like I said, the error is only generated every once in a while and NOT consistently. As such, you may have scores of variables that match scores of sessions with no errors. But then you add just one more and bingo you have an error that leaves you thinking "What the Hell just happened?"

What is further maddening is that after you fix that error, by changing then name of that conflict, you can go back to naming as you like until another error is generated. It happens only once in a while and not always.

Thanks for loaning me your memory.
