Php Server-like Page

[AndrewM16921]

So I was wondering if there is a way to create a server-like behavior with php. That is to say, a sort of "static" variable set that can be accessed and shared between all php sessions. And if this is possible, how would I go about setting it up?

 

Thanks

There is many way to persist data. You can use database,flat files. there is APC,memcached like extension which can store data in memory to share data between request. which one will be better is depend upon what you need to do actually.

I just wanted to create a sort of "active in last 15 min" list of my users. Seemed kind of weird to use a db for that. I'll have to look into this apc thing. o.O Thanks

You can store session data in database where there will be timestamp of last time update. after that getting last 15 minute would be trivial sql query. Check http://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCsQFjAA&url=http%3A%2F%2Fphp.net%2Fmanual%2Fen%2Fclass.sessionhandlerinterface.php&ei=jd_nUfSjAcW8rAfjv4FI&usg=AFQjCNFC98sy68egSNGfVuZkaDRxQ3G6mA&bvm=bv.49478099,d.bmk . APC would not be necessary for this.
