What is the significance of using the $GLOBALS['DOCUMENT_ROOT'] variable in PHP for file paths?

Using the $GLOBALS['DOCUMENT_ROOT'] variable in PHP for file paths is significant because it provides a consistent and reliable way to reference files on the server, regardless of the file's location within the directory structure. This variable returns the root directory of the server where the script is running, making it easier to construct file paths dynamically without hardcoding specific paths. 

// Constructing a file path using $GLOBALS['DOCUMENT_ROOT']
$file_path = $GLOBALS['DOCUMENT_ROOT'] . '/path/to/file.txt';
