cleanup php session files
php, session
Solution
To handle session properly, take a look at http://php.net/manual/en/session.configuration.php.
There you'll find these variables:
- session.gc_probability
- session.gc_divisor
- session.gc_maxlifetime
These control the garbage collector (GC) probability of running with each page request.
You could set those with ini_set() at the beginning of your script or .htaccess file so you get certainty to some extent they will get deleted sometime.
Problem
On my website I use PHP sessions. Session information is stored in files in my ./session path. After a few months I discovered that these session files are never deleted, by now there are 145.000 of them in this directory. How should these be cleaned up? Do I have to do it programmatically, or is ther a setting I can use somewhere that would have this cleanup happen automatically? EDIT forgot to mention: This site runs at a provider, so I don't have access to a command line. I do have ftp-access, but the session files belong to another user (the one the webserver proces runs I guess) From the first answers I got I think it's not just a setting on the server or PHP, so I guess I'll have to implement something for it in PHP, and call that periodically from a browser (maybe from a cron job running on my own machine at home)
