PHP library to manage Sign In with Apple identifier tokens, and validate them server side passed through by the iOS client.
Use composer to manage your dependencies and download php-apple-signin:
composer require griffinledingham/php-apple-signin<?php
use AppleSignIn\ASDecoder;
$clientUser = "example_client_user";
$identityToken = "example_encoded_jwt";
$appleSignInPayload = ASDecoder::getAppleSignInPayload($identityToken);
/**
* Obtain the Sign In with Apple email and user creds.
*/
$email = $appleSignInPayload->getEmail();
$user = $appleSignInPayload->getUser();
/**
* Determine whether the client-provided user is valid.
*/
$isValid = $appleSignInPayload->verifyUser($clientUser);
?>
