如何使用Goutte抓取div标签中的背景图像

composer require fabpot/goutte

<?php
require 'vendor/autoload.php';

use Goutte\Client;

$client = new Client();

$crawler = $client->request('GET', 'http://example.com');

$divsWithBackgroundImage = $crawler->filter('div[style*="background-image"]');
$backgroundImageUrls = [];

$divsWithBackgroundImage->each(function ($node) use (&$backgroundImageUrls) {
    $style = $node->attr('style');
    preg_match('/background-image:\s*url\((.*)\)/', $style, $matches);
    $backgroundImageUrl = $matches[1];
    $backgroundImageUrls[] = $backgroundImageUrl;
});

print_r($backgroundImageUrls);
