Question

For my project I have created a folder named DBAccess which holds all database related PHP files having PHP classes,constants functions etc.In the outside of the folder I have created a php file named DBAccess.php.
following is my directory structur in short

Project1
  |_DBAccess
  |       |_functions.php
  |       |_class.php
  |       |_constants.php         
  |_DBAccess.php
  |_index.php
  |_aboutus.php  
    .......

Now i wish to restrict any pages in the root directory to use the contents of the DBAccess folder except the DBAccess.php file.Is it posssible in PHP using .htaccess or something else?

You could do something like this:

DebugAccess/foo.php

<?php
$trace = debug_backtrace();

if (isset($trace[0])) {
  $dir =  basename(dirname($trace[0]['file']));
  $file = basename($trace[0]['file']);
  if ($file != 'DBAccess.php' && $dir != 'DBAccess') {
    throw new Exception("Nice try butthead");
  }
}

echo "Access Granted\n";

DBAccess.php

<?php
include_once("DBAccess/foo.php");

---

NoDBAccess.php

<?php
include_once("DBAccess/foo.php");

---

> php DBAccess.php 
Access Granted

> php NoDBAccess.php 

Fatal error: Uncaught exception 'Exception' with message 'Nice try butthead' in /Users/seanberry/so/DBAccess/foo.php:7
