Echo the ending part or last folder of $_SERVER['DOCUMENT_ROOT'] in PHP

Question

I need to use $_SERVER['DOCUMENT_ROOT']; to scandir for files and folders to display for my nav menu.

Let's say my root directory is at /home/user/public_html/website/.

Here's how I echo the root directory:

echo $_SERVER['DOCUMENT_ROOT'];

it will display /home/user/public_html/website/

Here's how I echo a folder in the root directory:

echo $_SERVER['DOCUMENT_ROOT'].'about/';

it will display /home/user/public_html/website/about/

Question: How can I strip everything that it displays all the way up to the root folder and/or sub-folder.

Example: If I echo $_SERVER['DOCUMENT_ROOT'], I want it to display as / instead of the entire /home/user/public_html/website/ path.

and if I echo a sub-folder I want it to display as /about/ instead of /home/user/public_html/website/about/.

So, how can I get it to echo just the ending part of the $_SERVER['DOCUMENT_ROOT']; instead of the entire directory path?

I've tried dirname and basename but neither of those does what I need. I've thought of string replace but isn't there something much easier to add onto $_SERVER['DOCUMENT_ROOT'] that will just echo out the root folder or root folder plus sub-folder?

Update:

I ended up using the answer below from anant kumar singh but tweaking it using preg_split instead of explode because preg_split can take multiple string delimiters where as explode can take only 1.

$newArray = preg_split( " (-in/|-ca/|-co/) ", dirname($_SERVER['DOCUMENT_ROOT']) );
if(count($newArray)>1){
    echo '/'.$newArray[1].'/';
    }else{
        echo '/';
    }

If you know of a better way to accomplish what I'm trying to do, please post your answers below.

You can go with explode in the following manner:--

$newArray = explode('website/',$_SERVER['DOCUMENT_ROOT']);
 if(count($newArray)>1){
   echo "/".$newArray[1];
}else{
    echo '/';
}

As you already said that preg_split is done the job for you:-

$newArray = preg_split( " (-in/|-ca/|-co/) ", dirname($_SERVER['DOCUMENT_ROOT']) ); if(count($newArray)>1){ echo "/".$newArray[1]."/"; }else{ echo '/'; }

NOTE:- Don't be panic.I am not going to take your credit. I just did it for the future peoples purpose. If you put it as an answer then i will remove it.
