This library aims to support:
RFC 5321, 5322, 6530, 6531, 6532.
- Composer is required for installation
- Spoofchecking and DNSCheckValidation validation requires that your PHP system has the PHP Internationalization Libraries (also known as PHP Intl)
Run the command below to install via Composer
composer require egulias/email-validator
EmailValidator
requires 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
- RFCValidation: Standard RFC-like email validation.
- NoRFCWarningsValidation: RFC-like validation that will fail when warnings* are found.
- DNSCheckValidation: Will check if there are DNS records that signal that the server accepts emails. This does not entails that the email exists.
- SpoofCheckValidation: Will check for multi-utf-8 chars that can signal an erroneous email name.
- MultipleValidationWithAnd: It is a validation that operates over other validations performing a logical and (&&) over the result of each validation.
- Your own validation: You can extend the library behaviour by implementing your own validations.
*warnings: Warnings are deviations from the RFC that in a broader interpretation are acceptded.
<?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()
]);
//ietf.org has MX records signaling a server with email capabilites
$validator->isValid("example@ietf.org", $multipleValidations); //true
It's easy! You just need to implement EmailValidation and you can use your own validation.
