Installation

You can install isBizMail via Composer:

composer require salaros/is-biz-mail

or by adding it directly to your composer.json file:

{
    "require": {
        "salaros/is-biz-mail": "*"
    }
}

Then use it like this:

<?php

require 'path/to/vendor/autoload.php';

use Salaros\Email\IsBizMail;

(new IsBizMail())->isValid('foo@bar.com');      // true

// You can use static access as well
IsBizMail::isValid('hello@gmail.com');          // false
// ...

You can easily drop it into your Yii2 model's rules:

public function rules() {
  return [
    // ...
    [['email'], 'isBusinessEmail'],
    // ...
  ];
}

public function isBusinessEmail($attributeName, $params) {
  $isBussiness = (new IsBizMail())->isValid($this->email);
  if (!isBussiness)
    $this->addError($attributeName, 'Mail boxes such as @gmail.com, @yahoo.com etc are not allowed!');
  return $isBussiness;
}
