What are the rules for configuring PHP pseudo-static?

The PHP rewrite rules for pseudo-static configuration are used in the server’s configuration file to convert dynamic URLs into static URLs, in order to improve the website’s SEO friendliness and user experience. The specific rules are as follows:

1. Firstly, make sure that the server has URL rewriting enabled. If you are using an Apache server, you will need to enable the mod_rewrite module.
2. Create a file named .htaccess in the root directory of the website (edit the file if it already exists), and add the following code to it:
3. Enable the Rewriting Engine and redirect all requests that are not for existing files or directories to index.php with the requested URL.
4. The first line indicates enabling URL rewriting function.
5. The second line indicates that if the requested file or directory exists, it will not be overwritten.
6. The third line indicates that all requests will be rewritten to the index.php file, with the original request passed as a URL parameter.
7. [QSA] indicates appending the query string of the original request to the rewritten URL.
8. [L] indicates the termination of the execution of subsequent rewrite rules.
9. Finally, save and upload the .htaccess file to the server.

By using the above configuration, for example rewriting http://example.com/article/123 as http://example.com/index.php?url=article/123, it achieves pseudo-static transformation of dynamic URLs. In PHP, the original request’s URL parameters can be obtained using $_GET[‘url’], and then the corresponding page or function can be processed based on that parameter.
