$$DOCUMENT_ROOT in PHP 4.2

[Anon]

Hello All,

I tried to work out $DOCUMENT_ROOT environment variable in PHP 4.2 on Apache 2.0.35. As you know that register global is Off(Register_global = Off) by default. How do I access to $DOCUMENT_ROOT without setting register global ON. If register global is ON, $DOCUEMNT_ROOT is working properly.

Thanks

You can use:
$_SERVER["DOCUMENT_ROOT"]

$_SERVER['DOCUMENT_ROOT'];
