</ul>

我只想从该内容中的每个锚标记中获取href值，然后将其放入数组中。

我该怎么做？

Answer 1

使用dom crawler symfony库。确保您有作曲家要安装它composer require symfony/http-foundation symfony/dom-crawler。有关更多详细信息，Dom crawler symfony Symfony HTTP Foundation

<?php
require_once '/path/to/vendor/autoload.php';

use Symfony\Component\DomCrawler\Crawler;
use Symfony\Component\HttpFoundation\Request;

$request = Request::createFromGlobals();

$request = new Request(
    $_GET,
    $_POST,
    [],
    $_COOKIE,
    $_FILES,
    $_SERVER
);

$request->query->get('link point to your get file');

$html = $request->getContent();

$links = [];

$crawler = new Crawler($html);

$anchors = $crawler->filter('body > a');

foreach ($anchors as $a) {
   $links[] = $a->href;
}

var_dump($links);

仅获取锚标记href值并将其放入数组
