Laravel 5 custom validation/how to control who can register

Hi, so first of all, my goal: I want to be able to control who can register for my web application. My app has a lot of work to do before it is ready for the public, but I want a few people I know to be able to use it. I assume I would do this with a custom validation? For example, I would have an array of email addresses and when a new user tries to register, check if their email address matches one in my array.

I have Googled around and a lot of the talk on Laravel custom validations is for Laravel 4. I have looked at the docs, and as I often find, the docs alone aren’t enough for me to grasp how to do something, in this case, a custom validation. But anyway...

So I suppose in app/Services/Registrar.php, within the validator function, I would do:

'email' => 'required|email|max:255|unique:users|MyCustomValidationRule'

and then somewhere (I don’t know where?), I would do:

Validator::extend(‘MyCustomValidationRule', function($attribute, $value, $parameters) {
     $accepted_emails = array(‘john@example.com’, ‘jane@example.com');
     //I don’t understand what to do from here-how I would use my array, and what the following line does (from the docs). 
     return $value == 'foo';
});

Can anyone help me with this please? Or is there an easier/better way to control who can register?

This worked for me:

Validator::extend('accepted_email', function ($attribute, $value, $parameters) {
    $accepted_emails = [
        'email1@example.com',
        'email2@example.com'
    ];
    $is_accepted = in_array($value, $accepted_emails);
    return $is_accepted;
});

Then I added accepted_email to the email value in the validator function in Registrar.php.
