使用Redmine的PHP API时，如何判断需求是否为原子需求

使用redmine的PHP接口时，怎样才能判断需求是否为原子需求呢，下面给出具体的做法:

    /**     * 判断是否为原子需求, 即是否依然含有子需求     * @param int $id 需求Id     * @return int     */    public function hasChildIssue($id)    {        $res = $this->client->api('issue')->show($id, array('include' => 'children'));        if (!empty($res) && isset($res['issue']['children'])) {            return true;        }        return false;    }

    set_time_limit(0);    $startTime = microtime(true);    //检查API KEY是否配置    $configService = $this->serviceInstance('config', 'work');    $config = $configService->getConstApiKey();    if (empty($config)) {        throw new \Exception('固定API KEY未配置');    }    $constApiKey = $config['value'];    $redmine = new RedmineLib($constApiKey);    $issueId=17252;    $temp = $redmine->client->get('/issues/'.urlencode($issueId).'.json?'.http_build_query(array ('include' => 'children')));    $temp = $redmine->client->api('issue')->show(17252, array ('include' => 'children'));    var_dump($temp['issue']['children']); exit; // 如果有子任务，['issue']['children']字段不存在，否则['issue']['children']字段对应一个子数组//        $temp  = $redmine->client->issue->show(17252, array('include' => 'children'));//        $temp  = $redmine->hasChildIssue(17330);    var_dump($temp); exit;
