Usage

Once you have email-verifier installed, you can use it to easily verify an email address. Email verification performs a number of checks to ensure a given email address is actually valid.

This library gives you access to all sorts of email verification data that you can use in your application in any number of ways.

<?php
require_once  __DIR__ . '/../vendor/autoload.php';

use WhoisApi\EmailVerifier\Builders\ClientBuilder;


$builder = new ClientBuilder();

$client = $builder->build('Your API key');

try {
    echo $client->getRawData('[email protected]', 'json') . PHP_EOL;
    /* Disable refreshing */
    echo print_r($client->get('[email protected]', ['_hardRefresh']), true) . PHP_EOL;
    
    $result = $client->get('[email protected]', ['_hardRefresh']);
    echo 'Email: ' . $result->emailAddress . PHP_EOL;
    echo 'Format: ' . ($result->formatCheck ? 'valid' : 'invalid') . PHP_EOL;
    echo 'DNS: '. ($result->dnsCheck ? 'resolved' : 'not resolved') . PHP_EOL;
    echo 'SMTP: ' . ($result->smtpCheck ? 'working' : 'not working') . PHP_EOL;
    echo 'Free: ' . ($result->freeCheck ? 'yes' : 'no') . PHP_EOL;
    echo 'Catch all: ' . ($result->catchAllCheck ? 'yes' : 'no') . PHP_EOL;
    echo 'Disposable: ' . ($result->disposableCheck ? 'yes' : 'no') . PHP_EOL;
} catch (\Throwable $exception) {
    echo "Error: {$exception->getCode()} {$exception->getMessage()}" . PHP_EOL;
}
