如何提取新闻<title>、、、使用<description>等？<category>foreach

这是我的代码：

<?php    

$movies = new SimpleXMLElement(file_get_contents("xml"));

foreach ($movies->channel->item->title as $title) {    
   echo $title, description, category,xxx,xxx,xxx, PHP_EOL;
   ####only one result echo!    
}    

?>

我的代码只能回显一个结果，我的意思是我有很多新的，如何获得它们？谢谢

您仅在第一个标题上进行迭代，因为您仅在第一个项目的第一个标题上进行迭代。

相反，您想遍历所有项目，然后获取每个项目的标题：

foreach ($movies->channel->item as $item)
{
    echo $item->title, PHP_EOL;
}

输出：

A01.Ad - 
A02.Ad -

就是这样，这通常在PHP Simplexml Basic Usage Examples中进行了概述，我建议您阅读那里以防卡住。
