# KeyNested
|
|
|
|
- `KeyNested(string $name)`
|
|
- `KeyNested(string $name, Validatable $rule)`
|
|
- `KeyNested(string $name, Validatable $rule, bool $mandatory)`
|
|
|
|
Validates an array key or an object property using `.` to represent nested data.
|
|
|
|
Validating keys from arrays or `ArrayAccess` instances:
|
|
|
|
```php
|
|
$array = [
|
|
'foo' => [
|
|
'bar' => 123,
|
|
],
|
|
];
|
|
|
|
v::keyNested('foo.bar')->validate($array); // true
|
|
```
|
|
|
|
Validating object properties:
|
|
|
|
```php
|
|
$object = new stdClass();
|
|
$object->foo = new stdClass();
|
|
$object->foo->bar = 42;
|
|
|
|
v::keyNested('foo.bar')->validate($object); // true
|
|
```
|
|
|
|
This rule was inspired by [Yii2 ArrayHelper][].
