Wordpress以什么方式重写页面URL？

Question

Recently I'm interested in post's structure of Wordpress.

They use a table named (wp_posts) and in this table they saved 3 related fields such as :

post_title
post_name
guid 

It's clear that they save title of each story in post_title field , and slugs in post_name , and full url of a post in guild filed .

But where the hell, they rewrite these urls in way it appears in browsers :

http://localhost/wordpress/about/

There is no htaccess rules for this !

I checked rewrite.php and didn't understand an inch ?!

i need to create similar pages , what steps should i take !?

The .htaccess file has a rewrite directive that sends all requests to index.php. The rewrite directive tells the web server to pass the original request to a different location without redirecting. So, index.php receives all the original parameters, including the request path (the part of the URL after the hostname, e.g., "/about/").

When index.php receives a request, it acts like a front controller, figuring out how to respond based on the URL.

I never looked at the inner workings of WordPress so I can't say exactly how they implemented it, but the general idea for index.php is this:

1. Look at the request path (e.g., "/about/") that the client used
2. Extract a slug from the request path ("about")
3. Look up which post has the slug "about"
4. Return the appropriate post
