Each

• v::each(v $validatorForValue)
• v::each(null, v $validatorForKey)
• v::each(v $validatorForValue, v $validatorForKey)

Iterates over an array or Iterator and validates the value or key of each entry:

$releaseDates = [
    'validation' => '2010-01-01',
    'template'   => '2011-01-01',
    'relational' => '2011-02-05',
];

v::arrayVal()->each(v::date())->validate($releaseDates); // true
v::arrayVal()->each(v::date(), v::stringType()->lowercase())->validate($releaseDates); // true

Using arrayVal() before each() is a best practice.
