Re: [PHP] Reading class variable value always returns NULL
Hi,
Thanks for your input Robert and Volmar! I have googled again with
"instance variable" instead of "class variable" - but have not found
any similar reports.
I'm pretty sure those are the same objects. The application usually
runs alright. We only see the instance variables becoming NULL since
about a week.
We had 3 small software upgrade coming from debian since we observe
the problem. We think they cannot be related. Still we have reverted
all of those and still see the problem.
Next step is that we setup a exact copy of the machine. Maybe it is a
hardware problem...
Thanks,

Hi, PHP APC 3.1.11 is marked beta, however it seems to contain important bugfixes. Is it safe to deploy on production (we're currently using 3.1.9)? Or it is better to wait for 'stable' release.

Re: [PHP] Reading class variable value always returns NULL
Hi,
We have since deployed another webserver machine and observe the exact
same behavior there.
So it is not a hardware problem.
We have also disabled various php modules, but this didn't help either.
Any debug suggestions are welcome! :)

Re: [PHP] Reading class variable value always returns NULL
I'm not real clear on what's happening. Are you saying that if you assign
values to the protected class members, and then immediately read them,
that they're null? So, there's code something like this:
class Foo {
public function Something() {
$this->foo = 1;
//shows null instead of 1
var_dump($this->foo);
}
protected $foo;
}
Is that right?

Bob

Re: [PHP] Reading class variable value always returns NULL
Hey,
We have:
error_reporting((E_ALL | E_STRICT) & ~(E_NOTICE | E_USER_NOTICE));
Displaying errors is disabled:
display_errors = Off
We have a custom error handler which logs all errors to a file.
In this file we receive byeffect errors, like that the second argument
to "array_key_exists" should be array, but is NULL. When we further
debug the reason is that the second argument is an instance variable,
and all instance variables are NULL.
We're pretty sure this is a software bug, since it only happens from
time to time, and already happens in the first line of the php script,
when none of our application code was loaded.
For example:
foo = 1;
if ($a->foo === null) {
throw new Exception("strange");
}
will throw an exception.
Since it only happens from time to time, it is really hard to debug.
We're now trying to reproduce in a virtual machine environment, while
replaying the actual requests that our webserver received. When we're
just simulating random load on the web server it doesn't happen. So it
must have something to do with certain requests, and they must have
some strange byeffect on php, or mod_php or something related.
Any input welcome!
Thanks,
Reto

Just to clarify, since at least 4.3.x subsequent calls session_start raise an E_NOTICE and are ignored, so you're first call is generating almost all the time.
