is_dir paths

Hello I am having trouble with is_dir I am trying to check whether /lists/admin/temp exists (which it does). However, I cannot get the function to work by specifying the path as above - it only works if I do it relative to the current working directory. So: var_dump (is_dir(getcwd())); var_dump (is_dir('temp')); #temp is one level below the working directory var_dump (is_dir("/lists/admin/temp")); returns bool(true) bool(true) bool(false) Thanks in advance Mark -- www.itsagoodprice.com - top-brand electronics for less.
