Requirements

Installation

Run the command below to install via Composer

composer require egulias/email-validator "~2.1"

Getting Started

EmailValidatorrequires you to decide which (or combination of them) validation/s strategy/ies you'd like to follow for each validation.

A basic example with the RFC validation

<?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
  2. NoRFCWarningsValidation
  3. DNSCheckValidation
  4. SpoofCheckValidation
  5. MultipleValidationWithAnd
  6. Your own validation

MultipleValidationWithAnd

It is a validation that operates over other validations performing a logical and (&&) over the result of each validation.

<?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 implement EmailValidation and you can use your own validation.
