Latest commit

* Reimplement DNSCheckValidation to utilise get_dns_record and extend support for detection of Null MX records (RFC7505) and reserved, mDNS and private namespaces (RFC2606 & RFC6762)

* Change valid email tests to use github.com instead of example.com as example.com now (correctly) fails the tests due to the Null MX case

* Tweak to pass CI psalm issue

* Encapsulate dns check code. Simplify local and reserved domain checks. Switch test domain

* Set PHPDoc return type

* Use strict comparisons

Build Status Coverage Status Scrutinizer Code Quality SensioLabsInsight

Suported RFCs

This library aims to support:

RFC 5321, 5322, 6530, 6531, 6532.

Requirements

Installation

Run the command below to install via Composer

composer require egulias/email-validator

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.
