Each

• Each(Validatable $ruleForValue)
• Each(null, Validatable $ruleForKey)
• Each(Validatable $ruleForValue, Validatable $ruleForKey)

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.
