Session Limit

[phpretard]

Is there a limit to how mant session variables can be set?

 

Any thoughts?

Again, you're limited by the session handler. If your OS has a limit

on the number of files in a single directory, that's your answer.

UNIX doesn't work real well with directories with large numbers

of files in them. I'd try to keep it well under 100,000 session

files. However, you can easily write a session handler that

stuffs sessions in a database table rather than in files. This

has advantages that the sessions can be accessed from multiple

round-robin servers serving the same content (for when you run

low on CPU power). That can probably handle a few hundred million

simultaneous sessions (but probably not the associated hit rate

unless you've got some really powerful hardware).

If I stuff them in a database how can I delete them when finished?

 

by the way... we are probably talking maybe 200 vars.

Database stuff will be relatively slower and occupy more space than the session stuffs,so I suggest u to go for session stuffs.
