How can the $_SERVER['DOCUMENT_ROOT'] variable be utilized to obtain the Unix path of a file on a network drive in PHP scripts?

To obtain the Unix path of a file on a network drive in PHP scripts using the $_SERVER['DOCUMENT_ROOT'] variable, you can concatenate the document root path with the relative path to the file on the network drive. This will give you the full Unix path to the file. 

$documentRoot = $_SERVER['DOCUMENT_ROOT'];
$networkFilePath = "/path/to/network/drive/file.txt";
$unixPath = $documentRoot . $networkFilePath;

echo $unixPath;
