Sorry, I mixed the expected and actual.
The expected result is false.

Description:
------------
The behaviour of the $depth parameter of json_encode() has changed when encoding objects.
On PHP 8.1, all three examples below successfully encode the input object, while
on PHP <= 8.0, json_encode() returns false as this exceeds the max depth.
Discussion: https://externals.io/message/116279
Demo: https://3v4l.org/DoG4A
If we replace the $a object with an empty array [], it works: https://3v4l.org/vFgh0
Test script:
---------------
// depth 1
$a = new \stdClass();
// depth 2
$b = new \stdClass();
$b->x = $a;
// depth 3
$c = new \stdClass();
$c->x = [$a];
var_export(json_encode($a, 0, 0)); echo "\n";
var_export(json_encode($b, 0, 1)); echo "\n";
var_export(json_encode($c, 0, 2));
Expected result:
----------------
'{}'
'{"x":{}}'
'{"x":[{}]}'
Actual result:
--------------
false
false
false
