我遇到了一些奇怪simplehtmldom的行为。
我$newlink从某个页面获取，然后将其放入另一个卷曲中，返回空白数据。如果我改变
curl_setopt($ch1, CURLOPT_URL, $newlink);
到
curl_setopt($ch1, CURLOPT_URL, "http://www.granma.cu/italiano/sport/22-noviembre-iaaf.html");
正在显示数据。我的错误在哪里？
<?php header("Content-Type: text/html; charset=utf-8"); ?>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php
require dirname(__FILE__) . '/simple_html_dom.php';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://youlichika.netii.net/aaa.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$htmls = curl_exec($ch);
curl_close($ch);
$html = str_get_html($htmls);
$newlink = $html->find('p',0);
echo $newlink;
