htaccess prevent direct page load

Question

I am trying to prevent direct access to all php files on my site except index.php using htaccess. I've got following code so far, however it still does not prevent form accessing php files directly.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ index.php?page=$1 [L]
</IfModule>

My Solution:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond $1 !^(index\.php|.*\.css|.*\.js|.*\.png|.*\.gif|.*\.jpg)
RewriteRule ^(.*)$ index.php?page=$1 [L]
</IfModule>

Answer 1

That's because of these lines:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Where you are explicitly telling the rewrite module to NOT run the following rules if the requested resource is a file or directory

However, I agree it's best to move them out of the web root entirely.
