validation for array in laravel code example

Example 1: how validate array in laravel in request

$validator = Validator::make($request->all(), [
    "names"    => "required|array|min:3",
    "names.*"  => "required|string|distinct|min:3",
]);

Example 2: in_array validation laravel

in:foo,bar,...

The field under validation must be included in the given list of values. Since 
this rule often requires you to implode an array, the Rule::in method may be 
used to fluently construct the rule:

'field' => 'required|in:' . implode(',', ['value1', 'value2']),
