New array validation rule required_array_keys

Laravel 8.82 adds a required_array_keys validation rule. The rule checks that all of the specified keys exist in an array.

Valid data that would pass the validation:

$data = [
    'baz' => [
        'foo' => 'bar',
        'fee' => 'faa',
        'laa' => 'lee'
    ],
];
 
$rules = [
    'baz' => [
        'array',
        'required_array_keys:foo,fee,laa',
    ],
];
 
$validator = Validator::make($data, $rules);
$validator->passes(); // true

Invalid data that would fail the validation:

$data = [
    'baz' => [
        'foo' => 'bar',
        'fee' => 'faa',
    ],
];
 
$rules = [
    'baz' => [
        'array',
        'required_array_keys:foo,fee,laa',
    ],
];
 
$validator = Validator::make($data, $rules);
$validator->passes(); // false
