如何使用Php检查网站是否启用了Amp

是否有一种常规方法来检查是否为URL启用了AMP

我目前使用Curl来获取HTML。 之后我该怎么办

$html;
if(AMP is Enabled)
    echo "You are using AMP in Mobile Version";
else
    echo "You are not using AMP in Mobile Version";

是的，你可以这样做

非AMP页面包含

<link rel="amphtml" href="https://www.example.com/url/to/amp/document.html">

    $dom = new DOMDocument();
    @$dom->loadHTML($html);

    $nodes = $dom->getElementsByTagName('link');
    foreach ($nodes as $node)
    {
        if ($node->getAttribute('rel') === 'amphtml')
        {
            echo($node->getAttribute('href'));
            /* amp page found do your logic */
        }
    }
