str_replace not replacing a url extracted from a database

I am trying to extract a filepath of an image from a MySQL database and turn it into a URL. However when I pass it through str_replace no changes are been made. I have set up a test document with a path preset and it works without any problems.

My code that extracts the path from the database is

$user_image = get_web_path($row['user_pic_path']);

where

function get_web_path($file_system_path) {
   return str_replace(var_dump($_SERVER['DOCUMENT_ROOT']), '', var_dump($file_system_path));
}

editted

My test code is:

<?php
   echo "DOCUMENT_ROOT: {$_SERVER['DOCUMENT_ROOT']}";
   $image_sample_path = "C:/wamp/www/website/images/image123.jpg";
   $web_image_path = str_replace($_SERVER['DOCUMENT_ROOT'], '', $image_sample_path);

   echo "<br /><br />CONVERTED PATH: {$web_image_path}";
?>

Which outputs:

   /website/images/image123.jpg"

However when extracting the value from the database, C:/wamp/www from the 'user_pic_path' field isn't being replaced.

var_dump('DOCUMENT_ROOT') gives

string 'C:/wamp/www' (length=11)

var_dump($file_system_path)) gives

string 'C:/wamp/www/website/images/image123.jpg' (length=39)

Why do you have curly braces around $_SERVER['DOCUMENT_ROOT'] ?

Try replacing that with:

str_replace($_SERVER['DOCUMENT_ROOT'], '', $file_system_path);
