User online

Megahertza

When a user logs on to my website a session variable "username" follows them arround. Can I make a list of a all the session[username] active. So I can make a Whos online script

I dont think so ... i may be wrong.

I think the only way is to add the user to a database table with the time they logged on. Every page visited should then update this time.

Then you just pull all users who were active in the last minute / 5 minutes (depending on how much page changing they do)

Can I save sessions to a different folder and then count the files

I don't have acces to a database but I can get 1, but I like to do most of my web with flat files. Its so i feel confident with php bf I move on to mysql. anyway if a future client only has php and no db, I'm there man

If you want to use a text file then instead of updating the database you could append the user on to the end of the text file with a time. Its a lot messier but possible.

Read the text file off

use : to seperate values

so your text file would have

user1:20.30
user2:20.32

read this off into two arrays
users[]
times[]

if your user is in users, say users[5]
then update times[5] and overwrite the text file
if the user isnt in the text file append $user.":".$time to it.

you could then use this to see who has been online in the last few minutes

Also you should do a check on old users and delete them so you dont have an enormous text file
