如何使用PHP Laravel显示RSS源描述中的图像

<?php

use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\View;
use Illuminate\Support\Str;

// 获取RSS源数据
$response = Http::get('https://example.com/rss-feed.xml');
$xml = simplexml_load_string($response->body());

// 遍历RSS项并提取图像URL
$items = [];
foreach ($xml->channel->item as $item) {
    $title = (string) $item->title;
    $description = (string) $item->description;
    $link = (string) $item->link;
    
    // 提取图像URL
    $image = '';
    if ($item->enclosure) {
        $image = (string) $item->enclosure['url'];
    } elseif ($item->image) {
        $image = (string) $item->image->url;
    } elseif ($item->children('media', true)->content) {
        $image = (string) $item->children('media', true)->content['url'];
    }
    
    $items[] = [
        'title' => $title,
        'description' => $description,
        'link' => $link,
        'image' => $image,
    ];
}

// 在视图中显示图像
return View::make('rss', ['items' => $items]);
