extract(filename)

In Borland Delphi, I can extract a filename from the paramstr(0) and then exchange out the extension. ChangeFileExt(extractfilename(paramstr(0)), '.html'); Is there a way to extract the filename of "/home/www/calendars/february2004.html" and swap its extension for .htm? february2004.htm is pure html. In february.html I include a header and a footer and then ("february2004.htm"); I would like to have some automatic code to do this instead of hand-coding 48 files. Do-able? How? I know these variables (PHP Version 4.3.4) but don't know how to start? $REQUEST_URI $_SERVER["REQUEST_URI"] $SCRIPT_NAME $_SERVER["SCRIPT_NAME"] $_SERVER["PHP_SELF"] $PHP_SELF Thanks, J
