check_num.cgi check_num is a very simple script that simply delivers a number from a text file to the php script running on the website for the script to print. This number is located in the file counter.txt, and represents the count of users having visited the site.
increment.cgi Used after the call to check_num.cgi, increment simply reopens the same text file used by check_num, counter.txt, and increments the value contained inside of it. This is accomplished by reading in and parsing the single number in the file, incrementing it, then overwriting the file with the new number.
time_check.cgi time_check.cgi will maintain and report the results of a time-based histogram located in the file histogram.txt. This file is formatted as eight entries of "hr1-hr2 val", where hr1 and hr2 are integers from 0 to 23 and val is some natural number representing the tally of visitors having visited between the hours outlined by hr1 and hr2.
time_check functions by first reading in all entries from the histogram file, then finding the relevant entry of these to the user's visiting time. The value associated with this range is then incremented, and the updated entry, as well as the other unused entries, are rewritten into the histogram file in the same format as they were originally found. The site visitor is then notified of their visiting time, as well as the current peak hour and tally associated with it.
