User:Dsimic/Traffic stats calculation
Automated monthly statistics calculation
[edit]Below is a rather simple PHP program that fetches monthly page views statistics provided by the Pageview API in JSON format (that's a public API developed and maintained by the Wikimedia Foundation, see also its detailed REST API documentation), for a specified list of articles, and calculates their total monthly views and average views per day. The fetched page views statistics don't include spider- or bot-generated traffic. The program is intended to be run interactively from a command-line interface (CLI); instead of running it locally, on a machine capable of executing PHP scripts, you may also use some of the freely available online PHP development environments.
Initially, this program used the page views statistics provided by stats
As pretty much everything else here on Wikipedia, I'm releasing this program code under the terms of the CC BY-SA 3.0 license, so please feel free to use it and modify according to your needs. Of course, feel free to use my talk page to in case you have any questions, suggestions, bug reports, etc.
Source code
[edit]Before running this program, you need to modify the list of articles contained in the $articles variable (what's in the code below is the list of articles I've created or started), and to modify the month and year for which statistics are to be fetched and calculated, which are specified through the FETCH_MONTH and FETCH_YEAR constants, respectively. When the program is configured to calculate statistics for the current month, it takes into account only the whole/elapsed days; as a result, running the program on the first day of the month to calculate current month statistics isn't supported. Also, in case whole days are missing in the statistics data available from the Pageview API, the program doesn't count in such zero-page-views days when calculating the averages. The FETCH_PROJECT constant selects the encyclopedia: en.wikipedia.org is for the English Wikipedia, de.wikipedia.org is for the German Wikipedia, etc.
Just as a note, getting ready-to-run PHP code of this program is as easy as viewing the Wiki code of this page and copying what's between the <syntaxhighlight lang="php" line> and </syntaxhighlight> tags. The program code below is the latest available version, and it is updated on this page after any improvements or bugfixes are implemented.

Output example
[edit]Below is an example of the output produced when the program from above is run. The program sorts the articles by their total page views in descending order, so the article that has received the largest number of page views is first in the printed list. In the Fetching statistics data line, dots (.) represent the progress updates during the processing of each article chunk, while the hash marks (#) represent the beginning of processing for each new article chunk. This chunking is necessary because the Pageview API imposes a rate limit on the API queries it receives, which, as of June 1, 2016[update], is specified at 10 requests per second.
