tracking DAILY web hits for summary reports

Hello, The boss wants PHP to compile hit stats day by day. Then he can type in 2 dates (start & end) and get a graph of all the hits per day. I am using a graphing class, which will work fine. But it needs a 2-d array of data to work. No sweat... I'm using a file-based solution, since the web server is outside the firewall and can't access our database. I have PHP opening a file, reading its contents (the # of hits), incrementing that # and re-writing that file. Each day there is a file, for example, 06-JUL-00.txt and 07-JUL-00.txt. Has anyone else had a similar project? My challenge has been to loop through, change the filename that I'm opening, without looking for 32-JUL-00 when it really wants 02-AUG-00. any help is appreciated :) -- Paul Fernandez Webmaster Structural GenomiX, Inc.
