PHP Email Address Validator: Validate email addresses using checklists

This package can validate email addresses using checklists.

It takes a given email address and checks if it may be possible to deliver messages to that address by connecting to the SMTP server that handles messages for the email address domain.

The package also checks the email address first against whitelist and blacklists, as well check if the email address domain is in a list of disposable email address domains.

Example

<?php
require dirname(__FILE__) . '/php-email-address-validator.php';

use PHPEmailAddressValidator\PHPEmailAddressValidator;

//Setting up lists.
PHPEmailAddressValidator::setWhiteListDatabasePath('whitelist.txt');
PHPEmailAddressValidator::setBlackListDatabasePath('blacklist.txt');
PHPEmailAddressValidator::setDisposableProvidersDatabasePath('disposable.txt');

$email = 'foo.bar@mail.com';
$disposable = 'foo.bar@yourdomain.com';

//Checking if the e-mail address is valid.
$result = PHPEmailAddressValidator::validateString($email);
echo 'Is a valid e-mail address? ' . ( $result === true ? 'Yes' : 'No' ) . PHP_EOL;

//Checking if the e-mail address is valid and existing.
$result = PHPEmailAddressValidator::validate($email);
echo 'Is a valid and existing e-mail address? ' . ( $result === true ? 'Yes' : 'No' ) . PHP_EOL;

//Checking if the e-mail address is accepted (its provider can be within the white list but not in the black list).
$result = PHPEmailAddressValidator::isTrustedProvider($disposable, false, true);
echo 'Is an accepted e-mail address? ' . ( $result === true ? 'Yes' : 'No' ) . PHP_EOL;

//Checking if the provider of the e-mail address is disposable or not.
$result = PHPEmailAddressValidator::isDisposableProvider($disposable);
echo 'Is a disposable e-mail address? ' . ( $result === true ? 'Yes' : 'No' ) . PHP_EOL;
