推荐答案

您要查看 curl 函数-它们将使您可以从另一个网站获取页面.您可以使用Cookie或HTTP身份验证先登录，然后再获取所需的页面，具体取决于您登录的网站.

You want to look at the curl functions - they will let you get a page from another website. You can use cookies or HTTP authentication to log in first then get the page you want, depending on the site you're logging in to.

拥有页面后，最好使用 正则表达式 抓取您想要的数据.

Once you have the page, you're probably best off using regular expressions to scrape the data you want.
