PHP检查用户是否查看了特定页面

Question

I am currently building web app in PHP where the client wants to have logged in users. There will be hierarchy so the new users won't have priviliges as higher positioned users. The priviliged users will be able to post articles and files for users to see.

This is my question: How can adminisitrator or the privileged user check who viewed the article or downloaded the files. Is this possible via PHP?

Answer 1

Of course it's possible, but you won't get it out of the box most likely. You'll need to store the access history for any given user server-side. You could do this by simply storing user ids, urls, and times in a seperate table in your database. Something along the lines of:

 5 | '/filedownload.php?file=cake-instructions.php' | 2012-02-15 08:23:11
 8 | '/company-information'                         | 2012-02-15 08:15:01

Anytime a user accesses a url, you store their id, that url, and the current time in a database. This would then be readily accessible to administrators if they want to perform queries to see who viewed what, and when.
