首先，列出您想要从中提取评论的网站。其次，通读这些网站，看看它们是否有开发人员部分以及是否公开公共 API。如果他们这样做，请四处看看他们是否有任何 php 客户端库，您可以使用它们从您的 php 站点访问他们的 API。如果他们确实有 API，但没有可用的客户端库，请通过创建客户端库并将其作为开源共享来为社区做出贡献。 :)
另外，他们可能有评论的 RSS 提要，您可以轻松地在您的网站上使用它，所以也请检查一下。
First, make a list of the sites that you want to pull reviews from. Second, read through those sites and see if they have a developer section and if they expose a public API. If they do, look around to see if they have any client libraries for php which you can use to access their API from your php site. If they do have an API but there are no client libraries available, contribute to the community by creating a client library and sharing it as open source. :)
Also, it may be possible that they have an RSS feed of their reviews that you can consume easily of your site, so check that out too.
您可能会发现其他网站已为此与 Google 合作，但我会使用 cURL 来获取您想要的信息。
我建议您从这里开始使用cURL，然后使用查看此处提取您所在的部分寻找 为了。

You will probably find the other sites have partnered with Google for this, however I would be using cURL to get the information you want.
I would suggest you start here with cURL, then have a look here to extract the portion you're looking for.
Edit: the section of the second link that is relevant is
What this is doing is getting the content you're looking for and then displaying it, you will probably need to define the unique elements with the content you want however, this could mean a separate rule for each website.
I hope this helps for you.
我认为谷歌通过站点地图找到新闻、博客、评论和类似的东西，网络管理员将其作为 sitemap.xml 引入谷歌。
为此，您必须获取您想要获取评论的页面内容（通过 CURL 或类似的方式获取远程文件）并通过 HTML 正则表达式获取评论
I think google find News, Blog , Reviews and something like that by site map what web administrators introduce to google as sitemap.xml .
To do this you must get page content what you want to fetch it's reviews ( By CURL or something like that to get remote file ) and fetch reviews by regular expression of HTML
