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:
<?php
class A{}
$a = new A();
$a->foo = 1;
if ($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.

This relates to a minor dilemma I come across from time and time, and
I'm looking for advice on pros and cons and best practice. Last night I
encountered it again.
Within a site I have a User object, and within page code would like to have
if ($crntUser->isASubscriber) {...}
There seems to be two ways to handle this:
I can have a User object method "getSubscriberStatus()" which sets
$this->isASubscriber. But to use this I would have to run the method
just before the if statement.
Or I could have a method "isASubscriber()" which returns the result,
meaning the if statement should be
if ($crntUser->isASubscriber()) {...}
While this is last night's specific example, I seem to face the
method-setting-variable or the method-returning-result-directly decision
quite often.
Is either of these approaches preferable, or does it simply not matter?
Thanks
Roddie Grant

or you just set User::$isASubscriber before.
or you can utilise __get()
I don't really get the problem. You can for example set the property right
after instanciation, or during instanciation (constructor).
$this->isASubscriber = !empty($subscriptions); // or something like that
