how to make php file looks like a directory???

[lnfreish]

such as:
http://www.domain.net/index.php/shopping/2002.shtml

I assume the index.php is a file, how can I use a script looks like it?

also, how can I use a PHP Scripts without extension, I don't want use directory, just like:
http://www.domain.net/news?id=23423

http://www.domain.net/news/2333.html

I expect the news is a file without extension , who can do it?

You need to learn how to configure Apache (or whatever you have). In Apache you will surely need to understand basics of mod_rewrite rules, and, optionally, ForceType directive. Look in Apache manual - these topics are covered there in details.

oh, I can do it in my own server, I only expect get a way for everyone who can't control the apache configuration.

Even at hosting you usually can write a .htaccess or write custom error404 page, which can serve your purposes as well.
