Как сконвертировать правила валидации LIVR для php?

SmilerOFF,

$rule="{
    'name': 'required',
    'email': ['required', 'email'],
    'gender': { 'one_of': ['male', 'female'] },
    'phone': {'max_length': 10},
    'password': ['required', {min_length: 10} ],
    'password2': { 'equal_to_field': 'password' }
}";
var_dump(json_decode($rule, 1));

Результат:
stdClass Object
(
[name] => required
[email] => Array
(
[0] => required
[1] => email
)

[gender] => stdClass Object
(
[one_of] => Array
(
[0] => male
[1] => female
)

)

[phone] => stdClass Object
(

)

[password] => Array
(
[0] => required
[1] => stdClass Object
(
[minlength] => 10
)
