Re: [PHP] Sessions running out of storage space - Increase memory?

Any ideas on how to fix this problem or a more elegant solution to my

APC?
apc_store('some_array',serialize($some_array),86400);
caches $some_array in RAM for 24 hours.
$some_array = unserialize(apc_fetch('some_array'));
brings it back out.
Note - don't do this if you're dealing with massive amounts of data
unique to each session_id, though. Come to think of it... if you're
dealing with massive amounts of data for each session_id, that might be
part of your problem. :)

Re: [PHP] Sessions running out of storage space - Increase memory?
It's already in an array format. I don't remember off the top of my head but there's some function like resultsarray which turns the resutls into an array. I'm already storing the array in the session.

The problem with that is would it be any faster or have any less strain on the server than having multiple requests/connections to the database? A lot depends on the amount of data and the overall load on the web-server. If you do the query once, then store the result in a file, and then keep reading that file for the next cachetime seconds, the file will most probably remain in memory, so accessing it will be fast and without IO. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Sessions running out of storage space - Increase memory?
Does the data change often? If not you could just enable query cache and cache connection threads and you'd probably be fine.

Re: [PHP] Sessions running out of storage space - Increase memory?
The data doesn't change often but the querys do. Thats why I was origionally thinking of just storing the entire result in a session and just use the part of the session I needed. So caching wouldn't really work. That was something intresting though that I didn't know earlier thanks! - Dan Gary Josack [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Does the data change often?
