How can the $_SERVER["DOCUMENT_ROOT"] variable impact the accuracy of file path references in PHP scripts for deleting folders and files?

The $_SERVER["DOCUMENT_ROOT"] variable contains the root directory of the server where the PHP script is running. When deleting folders and files in PHP scripts, using $_SERVER["DOCUMENT_ROOT"] in file path references ensures accurate and reliable paths regardless of the server environment. This variable helps in creating consistent file path references for deleting files and folders in PHP scripts.

$documentRoot = $_SERVER["DOCUMENT_ROOT"];
$folderToDelete = $documentRoot . "/path/to/folder";
$fileToDelete = $documentRoot . "/path/to/file.txt";

// Code to delete folder and file using $folderToDelete and $fileToDelete variables
