Exposed folders in MVC application

问题:

Well, as a start please excuse me for my beginner English..

I want to know more about security in PHP MVC applications

I've created my own MVC, I still haven't finished it.
My application directory is exposed by URL access with child elements.

How to make this hidden from visitors?

Following is what I am trying

Apache mod_rewrite ?

I still don't know to make it empty index.html in each folder like the framework Codeigniter ?

What to use for something to indicate ? and, ... how to make ?

Edit I know a litte something about rewrite_rules

Below is my .htaccess

    Options -MultiViews
    RewriteEngine On
    RewriteBase /ligia

    #RewriteCond %{REQUEST_FILENAME} -f [OR]
    #RewriteCond %{REQUEST_FILENAME} -l [OR]
    #RewriteCond %{REQUEST_FILENAME} -d
    #RewriteRule .+ -
    #I know, it is commented

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule "^(.+)$"    "index.php?uri=$1"   [QSA,L]

But I am afraid if this is the best way to hold my MVC application security!?

I need help!

First make sure that your .htaccess file is in your document root (the same place as index.php) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).

Next make a slight change to your rule so it looks something like:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]

At the moment you're just matching on . which is one instance of any character, you need at least .* to match any number of instances of any character.

If you want the whole shebang installed in a sub-directory, such as /mvc/ or /framework/ the least complicated way to do it is to change the rewrite rule slightly to take that into account.

RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]

And ensure that your index.php is in that folder whilst the .htaccess file is in the document root.

NC = No Case (not case sensitive, not really necessary since there are no characters in the pattern)

L = Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)

QSA = Query String Apend, just in case you've got something like ?like=penguins on the end which you want to keep and pass to index.php.
