PHP如何创建新的html页面？ [关闭]

Question

As many of you know when someone creates a StackOverflow question a new page is generated and it is visible in the various search engines as well. I was wondering how PHP code created these pages. It turns out that most websites like this have one page, something like profile.php and it loads the data from a MySQL database. My question is as follows: If there is only one physical file how can the URL change and how does google list all of the pages/profiles/question from sites like StackOverflow or Facebook if there is only one actual page?

Answer 1

You tell search engines 'Google, Bing, ..etc' for example to see your website by giving them sitemap.xml listing your pages, allow their web-bots (spider) access too the site and crawl the data and links, you may have one page like posts.php and it is different with parameters posts.php?id=123 or posts.php?name=mypost

Edited: If you want use one file posts.php and make site http://domain.com/posts/posttitle you need to apply Front Controller Pattern site point link and this implies setting you server Apache/Nginx to redirect the requests to one file (URL rewrite) and this file contain the logic for handle the request or use MVC framework
