A library for validating emails against several RFC.
This library aims to support RFCs:
| Version | Released | EOL | Only critical bug fixes | Full |
|---|---|---|---|---|
| v4.x | 2023/01/07 | - | X | X |
| v3.x | 2020/12/29 | YES | ||
| v2.1.x | 2016/05/16 | YES | ||
| v1.2 | 2013/19/05 | YES |
- PHP 8.1
- Composer is required for installation
- Spoofchecking and DNSCheckValidation validation requires that your PHP system has the PHP Internationalization Libraries (also known as PHP Intl)
Note: PHP version upgrades will happen to accomodate to the pace of major frameworks. Minor versions bumps will go via minor versions of this library (i.e: PHP7.3 -> v3.x+1). Major versions will go with major versions of the library
Run the command below to install via Composer
composer require egulias/email-validatorEmailValidator 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("[email protected]", 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 entail that the email exists.
- MultipleValidationWithAnd: It is a validation that operates over other validations performing a logical and (&&) over the result of each validation.
- MessageIDValidation: Follows RFC2822 for message-id to validate that field, that has some differences in the domain part.
- 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 accepted.
<?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 capabilities
$validator->isValid("[email protected]", $multipleValidations); //trueValidations not present in the RFCs
- SpoofCheckValidation: Will check for multi-utf-8 chars that can signal an erroneous email name.
It's easy! You just need to implement EmailValidation and you can use your own validation.
