Cast a class instance (object) to associative array creates strange keys

I have a class with protected variables

class MyClass {
  protected $moo;
  protected $foo;
}

so when I try to encode an instance to json the result omits the protected vars.

Because of that I first use

$arr =  (array) $instance;

but than the keys are strange *moo, *foo and I have to

join(explode('\u0000*\u0000',json_encode($arr, JSON_FORCE_OBJECT)));

Any suggestion how to avoid these strange symbols in the first place?

Can you change your class definition? – u_mulder Sep 07 '18 at 11:53
how's you created `$instance`? and what's the output of `var_dump($arr);` after this line `$arr = (array) $instance;`? – Alive to die - Anant Sep 07 '18 at 11:54
Thats because the properties are `protected` – RiggsFolly Sep 07 '18 at 11:55

If you can modify your class `myClass` I advise you to add `JsonSerializable` implementation to it. – u_mulder Sep 07 '18 at 11:58
