PHP 有一个简单的命令来获取网页的元标记（get_meta_tags），但这仅适用于具有名称属性的元标记。然而，开放图谱协议如今变得越来越流行。从网页获取 opg 值的最简单方法是什么？例如：
<meta property="og:url" content="">
<meta property="og:title" content="">
<meta property="og:description" content="">
<meta property="og:type" content="">
我看到的基本方法是通过 cURL 获取页面并使用正则表达式解析它。任何想法？
非常简单而且做得很好：
Using https://github.com/scottmac/opengraph https://github.com/scottmac/opengraph
$graph = OpenGraph::fetch('http://www.avessotv.com.br/bastidores-pantene-institute-experience-pg.html');
print_r($graph);
将返回
