This is in response to Matt Stauffer's blog post Form array validation in Laravel 5.2.

At the end Matt explains that you can apply validation rules to a specific array index, he also says that he is "Not sure why you would do this, but, it's possible".

One scenario I have thought of is when you need to require at least one value for a multiple value field, for example a user can have many email addresses.

$this->validate($request->all(), [
  'email_addresses.1' => 'required|email',
  'email_addresses.2' => 'email',
]);

Or if a user can have multiple social websites associated with their account.

$this->validate($request->all(), [
  'social_profiles.twitter.*' => 'regex:^@?(\w){1,15}$',
  'social_profiles.facebook.*' => 'regex:<facebook regex>'
]);

I'm sure there are other examples and definitely other ways of doing the above examples, but hopefully this is food for thought.
