Example:

$MadelineProto = new \danog\MadelineProto\API();
if (isset($token)) {
    $this->bot_login($token);
}
if (isset($number)) {
    $sentCode = $MadelineProto->phone_login($number);
    echo 'Enter the code you received: ';
    $code = '';
    for ($x = 0; $x < $sentCode['type']['length']; $x++) {
        $code .= fgetc(STDIN);
    }
    $MadelineProto->complete_phone_login($code);
}

$AuthState = $MadelineProto->checkAuthCode(['code' => string, 'first_name' => string, 'last_name' => string, ]);

Or, if you're into Lua:

AuthState = checkAuthCode({code=string, first_name=string, last_name=string, })
