9740e24007Version 3.0 will include a few crucial deprecations. This commit adds some soft deprecations to warn users about these changes. Some of the biggest changes are: * The method `validate()` will be renamed to `isValid()`. * The method `validate()` will be repurposed to return an object with failures. * It won't be possible to handle rules directly; users will need to use the `Validator` class to validate with any rule. There will some more changes, but those are some of the most important ones, and are the ones that are easy to deprecate right now.

# 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
|
|
$array = [
|
|
'foo' => [
|
|
'bar' => 123,
|
|
],
|
|
];
|
|
|
|
v::keyNested('foo.bar')->isValid($array); // true
|
|
```
|
|
|
|
Validating object properties:
|
|
|
|
```php
|
|
$object = new stdClass();
|
|
$object->foo = new stdClass();
|
|
$object->foo->bar = 42;
|
|
|
|
v::keyNested('foo.bar')->isValid($object); // true
|
|
```
|
|
|
|
This rule was inspired by [Yii2 ArrayHelper][].
