Count total session values

[petenaylor]

Hi all

 

I have a site whereby people login to their accounts and each time they do it enters this into the session:

 

$_SESSION['wmmadmin_email'] = "".$user_login."";

 

I now need to count each of these session variables and show a total on my site?

 

How do I count them and show a total?

 

Many thanks

You mean count how many sessions there are? That's not so simple, as when your code executes you only have access to that specific user's session within the $_SESSION array. Session data by default is stored within individual files within a directory on the server, so counting the files is very inefficient.

 

Since you have users, I'm assuming you also have a users database table to validate their username/password? Extend this table by adding a new column that stores a timestamp of their last activity (last page request). Using this timestamp you can then query for users that have been active in the last 5 minutes or so, and efficiently get an accurate count of active users.
