PHP : Set document root to be a subdirectory without .htaccess or Virtualhost

PHP : Set document root to be a subdirectory without .htaccess or Virtualhost
Recently I faced a problem with hosting a website on a server to which I have limited access. I was provided with permission only to a sub-directory on the server.
I'm habituated to use relative paths, but my root points to the root of server and not my sub-directory. This forced me to use absolute paths at every point.
I searched for the solution and end up with two results:
.htaccess ot Virtualhost
I never tried to understand .htaccess and I don't have access to set Virtualhost. This forced me to try bit harder and here is the outcome.

I've created a file named rootpath.php on root directory of my website.
(Note: this is not root '/' of the web server, but my sub-directory)
Its contents are as follows:
<?php
    $relative_path = "/subdirectory";
    $server_url = $_SERVER["SERVER_NAME"];

    $root = "http://" . $server_url. $relative_path;
?>
Now, I include this file on top of every file.
Eg: <?php require('rootpath.php'); ?>
and append all paths with <?php print $root; ?>
Eg: <a href="<?php print $root; ?>/index.php">
Note: Initially I used './' and '../' notation, but it won't work always. Consider the following case, which I faced:
/index.php
/header.php
/footer.php
/scripts.php
/contact
--contact/contact.php
I defined a common header for all the pages and stored it in header.php, which in-turn imports all the necessary scripts from scripts.php.
Now, if you import header.php from contact/contact.php, it work work properly because scripts.php is loaded relatively in header.php and now the control searches it in contact directory.

Ubuntu: Access a usb flash drive from the terminal

    1. Find what the drive is called You'll need to know what the drive is called to mount it. To do that fire off: sudo fdisk -l You're looking for a partition that should look something like:   /dev/sdb1 . Remember what it's called. 2.

Karabiner: Mouse/keyboard customizer for OS X

For beginners, or the one who migrated from Windows environment, Natural Gestures (Scrolling and Swiping) might be bit confusing. But, once you get familiarized with them, it may feel like "What was I doing, all those days?". It all changed, when I connected external mouse to my Macbook. When you start using that WHEEL, you will be confused. Luckily there is a setting for mouse, to change scroll behavior (natural or the other way). But, here's the catch. If you toggle that setting, it also toggles the same for TRACKPAD!!!!! I've seen that many people were freaked out and even raised BUG report to Apple. But, all those reports were closed, saying that is not a bug, but intentional feature!!! For those, who can't leave with such one-sided settings, here is a simple util, which came to my rescue: Karabiner It's simple, powerful and stable mouse/keyboard customizer for OSX. Without going into much detail, here's the configuration I used to ret

Java: Use BigInteger in for-loop

In my previous post , I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it: Ordinary integers: for(int i = 1; i <= n; i++) {  //Task to do } BigInteger: for (BigInteger bi = BigInteger.valueOf(1);                 bi.compareTo(n) <= 0;                 bi = bi.add(BigInteger.ONE)) { //Task to do } here n is a BigInteger variable.
