realpath($_SERVER["DOCUMENT_ROOT"]) not working on Windows

Question

I get this error: Warning: require_once(C:\xampp\htdocs/models/config.php): failed to open stream: No such file or directory in C:\xampp\htdocs\venture\html\admin\index.php on line 3

Here is the code where the error appears:

$root = realpath($_SERVER["DOCUMENT_ROOT"]);
require_once($root . "/models/config.php");

Answer 1

you need change slash

$root = realpath(str_replace('\\', '/', $_SERVER['DOCUMENT_ROOT']) );
require_once($root . "/models/config.php");
