通过index.php（包括图像，CSS等）路由每个请求

Question

(php newbie here)

I'm writing a very simple router for a mostly static marketing website. So far, I have every request that doesn't match a file go through my index.php.

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule . /index.php [L]
</IfModule>

And in my index.php, I decide what to output. This is working pretty well.

But what happens if a user browses specifically to a file I don't want them to go to? It won't go through my index.php. So I could remove that condition... but what about css files? I'm guessing I could include those as well. But then... what about images?

I'm guessing there's a better way that I just don't know about yet.

(One request: Please don't suggest using a framework. I'd like to learn how things work before I use somebody else's code.)

Change the Rewrite condition to include a list of excluded filetypes:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !\.(png|jpg|gif)$
    RewriteRule . /index.php [L]
</IfModule>
