root directory

I have a file that I am including and in it I have a call to open a file from the temp_csv directory located in the main directory. Now I am running into problems when the included file is included from a file outside the main directory. Is there a way to have the path to the file open absolute? I know ../ backups up one directory, does ./ take you to the absolute path? Thanks -- ---------- Greetings Jedi - http://lastjedi.org
