推荐答案

最简单的方法:

file_get_contents()

这将为您提供网页的来源.

That will get you the source of the web page.

不过，您可能想要更完整的内容，因此请查看 cURL，为了更好的错误处理，以及设置用户代理等等.

You probably want something a bit more complete though, so look into cURL, for better error handling, and setting user-agent, and what not.

从那里开始，如果您只想要文本，您将不得不解析页面.为此，请参阅:您如何在 PHP 中解析和处理 HTML/XML?

From there, if you want the text only, you are going to have to parse the page. For that, see: How do you parse and process HTML/XML in PHP?
