``get_object_vars`` leaks class in property when used for class with property getter

[gielwijgergangs]

Description

The following code:

<?php

class Example implements JsonSerializable
{
    public function __construct(
        private array $authors,
    ) {}

    public string $credits {
        get {
            return implode(', ', $this->authors);
        }
    }
    
    public function jsonSerialize():mixed{
        return get_object_vars($this);
    }
}

$obj = new Example(['test', 'test2']);
echo json_encode($obj);
    

Resulted in this output:

{"\u0000Example\u0000authors":["test","test2"],"credits":"test, test2"}

But I expected this output instead:

{"authors":["test","test2"],"credits":"test, test2"}

Without the getter it does serialize as expected:

The following code:

<?php
class Example implements JsonSerializable
{
    public function __construct(
        private array $authors,
    ) {}

    public function jsonSerialize(): mixed
    {
        return get_object_vars($this);
    }
}

Results in

{"authors":["test","test2"]}

serialize() yields (

O:7:"Example":2:{s:16:"Exampleauthors";a:2:{i:0;s:4:"test";i:1;s:5:"test2";}s:7:"credits";s:11:"test, test2";}

so this is an engine issue, not JSON specific.

get_object_vars will call zho_build_properties_ex which normally uses the mangled names as keys.

@cmb69 you are right. The issue is not related to JSON, apologies for the confusion. I modified the title of the issue.

Maybe @iluuu1994 can have a look?
