Deny direct access to all .php files except index.php

Question

I want to deny direct access to all .php files except one: index.php

The only access to the other .php files should be through php include.

If possible I want all files in same folder.

UPDATE:

A general rule would be nice, so I don't need to go through all files. The risk is that I forget a file or line.

UPDATE 2:

The index.php is in a folder www.myadress.com/myfolder/index.php

I want to deny access to all .php files in myfolder and subfolder to that folder.

Answer 1

You can try defining a constant in index.php and add something like

if (!defined("YOUR_CONSTANT")) die('No direct access');

to the beginning of the other files.

OR, you can use modrewrite and redirect requests to index.php, editing .htaccess like this:

RewriteEngine on
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L]

Then you should be able to analyze all incoming requests in the index.php and take according actions.

If you want to leave out all *.jpg, *.gif, *.css and *.png files, for example, then you should edit second line like this:

RewriteCond $1 !^(index\.php|*\.jpg|*\.gif|*\.css|*\.png)

Answer 2

In index.php, add an access value like this:

$access = 'my_value';

In every other file, include this check before even a single byte is echoed out by php:

if (empty($access)) {header("location:index.php");}

This way, other php files will be accessible only through require / include and not through the url.

Answer 3

Are you sure, you want to do that? Even css and js files and images and ...?

OK, first check if mod_access in installed to apache, then add the following to your .htaccess:

Order Deny,Allow
Deny from all
Allow from 127.0.0.1

<Files /index.php>
    Order Allow,Deny
    Allow from all
</Files>

The first directive forbids access to any files except from localhost, because of Order Deny,Allow, Allow gets applied later, the second directive only affects index.php.

Caveat: No space after the comma in the Order line.

[EDIT:]

To allow access to files matching *.css or *.js use this directive:

<FilesMatch "*\.(css|js)$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

You cannot use directives for <Location> or <Directory> inside .htaccess files, though.

Your option would be to use <FilesMatch "*\.php$"> around the first allow,deny group and then explicitely allow access to index.php.

Answer 4

How about keeping all .php-files except for index.php above the web root? No need for any rewrite rules or programmatic kludges.

Adding the includes-folder to your include path will then help to keep things simple, no need to use absolute paths etc.

Answer 5

An oblique answer to the question is to write all the code as classes, apart from the index.php files, which are then the only points of entry. PHP files that contain classes will not cause anything to happen, even if they are invoked directly through Apache.

A direct answer is to include the following in .htaccess:

<FilesMatch "\.php$">
    Order Allow,Deny
    Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

This will allow any file like index.php, index2.php etc to be accessed, but will refuse access of any kind to other .php files. It will not affect other file types.
