How Can I Prevent Direct Access to Files While Still Including Them in My Main PHP File Using .htaccess?

Restricting Direct Access to Files Using .htaccess

To prevent direct access to specific files or directories, .htaccess files can be utilized. This is especially useful for safeguarding sensitive data or resources. Let's address a scenario where you wish to restrict access to an 'includes' folder and a 'submit.php' file while allowing their inclusion in 'index.php'.

To achieve this, follow these steps:

1. Create a .htaccess File in the 'includes' Folder:

   In the 'includes' directory, create a file named '.htaccess' (note the leading dot) and populate it with the following code:

   deny from all

   This instructs the server to deny access to all files within the 'includes' directory.

2. Create a .htaccess File in the Root Folder:

   In the website's root directory, create a '.htaccess' file and add the following rule:

   RewriteEngine On
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . index.php [L]

   This code ensures that any request for a file or directory in the root that does not exist is redirected to 'index.php'. This prevents direct access to 'submit.php'.

3. Include Files in 'index.php':

   In 'index.php', include the files from your 'includes' directory as needed without any restrictions. The .htaccess file in the 'includes' folder will prevent direct access to these files externally, while your PHP code will be able to utilize them without issue.
