=============================
With the help of [PHPStorm](https://www.jetbrains.com/phpstorm/)
## Requirements ##
* [Composer](https://getcomposer.org) is required for installation
* [Spoofchecking](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/SpoofCheckValidation.php) validation requires that your PHP system have the [PHP Internationalization Libraries](http://php.net/manual/en/book.intl.php) (also known as PHP Intl)
## Installation ##
Run the command below to install via Composer
```shell
composer require egulias/email-validator "~2.1"
```
## Getting Started ##
`EmailValidator`requires you to decide which (or combination of them) validation/s strategy/ies you'd like to follow for each [validation](#available-validations).
A basic example with the RFC validation
```php
<?php
use Egulias\EmailValidator\EmailValidator;
use Egulias\EmailValidator\Validation\RFCValidation;
$validator = new EmailValidator();
$validator->isValid("example@example.com", new RFCValidation()); //true
```
### Available validations ###
1. [RFCValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/RFCValidation.php)
2. [NoRFCWarningsValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/NoRFCWarningsValidation.php)
3. [DNSCheckValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/DNSCheckValidation.php)
4. [SpoofCheckValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/SpoofCheckValidation.php)
5. [MultipleValidationWithAnd](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/MultipleValidationWithAnd.php)
6. [Your own validation](#how-to-extend)
`MultipleValidationWithAnd`
It is a validation that operates over other validations performing a logical and (&&) over the result of each validation.
```php
<?php
use Egulias\EmailValidator\EmailValidator;
use Egulias\EmailValidator\Validation\DNSCheckValidation;
use Egulias\EmailValidator\Validation\MultipleValidationWithAnd;
use Egulias\EmailValidator\Validation\RFCValidation;
$validator = new EmailValidator();
$multipleValidations = new MultipleValidationWithAnd([
new RFCValidation(),
new DNSCheckValidation()
]);
$validator->isValid("example@example.com", $multipleValidations); //true
```
### How to extend ###
It's easy! You just need to extend [EmailValidation](https://github.com/egulias/EmailValidator/blob/master/EmailValidator/Validation/EmailValidation.php) and you can use your own validation.
