How to count the number of unique visitors per day? Just create an empty file
analytics.log and add this simple logging code at the end of
<?php $txt = date("Y-m-d") . "\t" . date("H:i:s") . "\t" . $_SERVER['REMOTE_ADDR'] . "\t" . $_SERVER['REQUEST_URI'] . "\t" . $_SERVER['HTTP_USER_AGENT'] . PHP_EOL; file_put_contents('./analytics.log', $txt, FILE_APPEND); ?>
python analytics.py with this Python code will display the number of unique visitors for each day, in a human readable way:
import csv S = dict() with open('analytics.log', 'rb') as f: reader = csv.reader(f, delimiter='\t') for row in reader: if row not in S: # row is the date in year-month-day format S[row] = set() # let's use a set in order to count each IP only once a day S[row].add(row) # row is the IP for k in sorted(S): print k + ': ' + str(len(S[k]))
The result will look like this:
2015-04-19: 226 2015-04-20: 326 2015-04-21: 303
If the number of visitors per day is enough for you (it is for me), you don't need to use Google Analytics. Let's keep it simple and stupid!
