What are some common variations in document root names across different servers that should be considered when manipulating paths in PHP?

When manipulating paths in PHP, it's important to consider variations in document root names across different servers. One common variation is the use of "htdocs" or "public_html" as the document root directory. To ensure portability and compatibility, it's recommended to dynamically determine the document root path using PHP's $_SERVER['DOCUMENT_ROOT'] superglobal. 

$document_root = $_SERVER['DOCUMENT_ROOT'];
$path = $document_root . '/path/to/file';
