According to the docs(https://www.php.net/manual/en/language.oop5.basic.php), $this is a reference
to the calling object. Though, there is a mention of a different behaviour for the static context,
I'm sure it's only related to static(methods and properties), which is a different thing.
Looking at the docs for static
variables(https://www.php.net/manual/en/language.variables.scope.php#language.variables.scope.static),
there is no mention of how $this is treated. As it only mentions that variables are saved by
reference, I think it will be reasonable for someone to expect a special treatment for
$this(considering it's not an ordinary variable, but pseudo-variable)

As indicated by the $, yes.

How did you get that impression in the first place? If the documentation suggested so, that needs to
be fixed.

So it appears that $this is considered a variable rather than being resolved dynamically as a
reference to the current calling object in a context of local static variable.
In my opinion this is not a straightforward behaviour. So $this either needs to be fixed(dynamic
resolution), or this(behaviour) should be documented.

$testMap is initialized using the setC/setD methods on $this, which is $a1 at that time.

Description:
------------
Hi,
so if property assignment is done through call_user_func, it will only work for the first call, but
will fail for all next(see var_dump output in the example).
Also, if I would assign through dynamic method name call ($this->{$methodName}($prop)), it will
work fine.
Test script:
---------------
https://3v4l.org/ta03s
Expected result:
----------------
All instances of A class should have defined(not-null)C properties
Actual result:
--------------
Only the first instance of A class has it defined, while other do not.
