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

推荐答案

是的，您可以这样做

非AMP页面包含

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

假设您的内容位于$ html;

Assuming that you have the content in $html;

PHP代码

    $dom = new DOMDocument();
    @$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 */
        }
    }
