我的问题是，我想从大型HTML代码获得此内容： 包含href标记的所有其他标记均不可见！
<a href="/admin/home" torero-icon="home">Home</a>
在这里，我想首先获得“ / admin / home”，然后获得整个标签“ 主页”
<a href="#" torero-icon="add" torero-left-icon="accessibility">Account Verwaltung</a>
在这里，我要首先获取“＃”，然后再获取整个标签“ 帐户注册“ < / p>
感谢您的帮助人员：）

我正在研究类似的东西：
$urls = preg_match_all('#\bhttps?://[^,\s()<>]+(?:\([\w\d]+\)|([^,[:punct:]\s]|/))#', $page, $urls);
这将获取所有URL，但是要获取所有href，您需要将正则表达式更改为一个以完善所需的内容。
然后，您可以使用foreach语句遍历结果：
foreach ($urls as $url){
echo "url: " . $url;
}

我找到了一些能完成技巧的事情：
preg_match_all('<a href="(.*)" (.*)>',$text,$match);
导致：

如果这是一个简单的字符串，请使用strstr或preg_match_all。如果您有完整的HTML文档，请使用PHP的内置DOMDocument。考虑：
$page_html = "<!DOCTYPE html>\n<html>\n...</body>\n</html>";
$doc = \DOMDocument::loadHTML( $page_html );
$anchors = $doc->getElementsByTagName('a');
foreach ( $anchors as $a )
echo "Anchor HREF: " . $a->getAttribute('href') . PHP_EOL;
如果没有适当的标记化，基于字符串的方法将丢失边缘情况。例如，您要如何处理注释掉的锚点？还是不完全遵循您期望的形式的锚呢？ DOMDocument解析器应该完全捕获您想要的内容。
