This is already documented (with example showing the difference between

I don't understand your issue, every variable type is passed by value,
unless the function definition explicitly says it has to be passed by
reference.

Checked on these snaps, no changes.

Well, maybe this is due to incorrect understanding of what object
passing by reference means? Maybe this is a documentation problem?

I've added detailed explanation here:

Description:
------------
I make one object instance. Then, pass it to another object. Then,
change original instance. Now I have two different objects.

Reproduce code:
---------------
<?php
class classA {
    public $id = "";
    public function __construct($id) {
        $this->id = $id;
    }
}
class classB {
    public $reference = null;
    public function __construct($ref) {
        $this->reference = $ref;
    }
}
$a = new classA("object 1");
$test = new classB($a);
$a = new classA("object 2");
echo $a->id, "<br>", $test->reference->id;
?>

Expected result:
----------------
object 2
object 2

Actual result:
--------------
object 2
object 1

However, adding references solves the problem:

class classB {
    public $reference = null;
    public function __construct(&$ref) {
        $this->reference =& $ref;
    }
}

This works as expected.

So, the question is are objects being passed by reference or what?
