Я пытаюсь выполнить итерацию объекта ниже, используя foreach в PHP, но я не получаю никакого результата.Почему isset и не пустой не работает в этом объекте Solarium iteration

Я использую следующий PHP код
<?php
if($this->totalResults > 0) {
foreach($this->results as $result) {
//if(!empty($result->title) && !empty($result->url) && !empty($result->description)) {
if(isset($result->title) && isset($result->url) && isset($result->description)) {
?>
<div class="search_result">
<a class="title" href="#">
<?php echo $result->title[0];?>
</a><br/>
<span class="url">
<?php echo $result->url;?>
</span><br/>
<span class="description">
<?php echo $result->description;?>
</span>
</div>
<?php }
}
}?>
Я никогда не получаю никакого результата, но я должен получить последний узел, поскольку он содержит заголовок, URL и описание ключей.
Но когда я просто положить
if($result->title && $result->url && $result->description) {
Затем он работает отлично. Почему он не работает в этом режиме.
Я редактирую вопрос и размещаю весь объект –
