$DOCUMENT_ROOT -- didn't work from a class..

Hello gurus! In one of my classes that I'm currently writing I'm trying to output $DOCUMENT_ROOT as simple as that... echo 'HERE->>>'.$DOCUMENT_ROOT.'<br>'; but because it is inside a function which is called from the main script, it does not output anything except HERE->>> What can be the problem? Why it happens inside the class and not on a simple php file? If I don't mistake language_variables_predefined_apacheApache variables once they are activated should work no matter what the extension of the file is as long as they are includ()ed, right? Greatly appreciate your help. Maxim Maletsky - maxim@j-door.com <mailto:maxim@j-door.com> Webmaster, J-Door.com / J@pan Inc. LINC Media, Inc.
