Override garbage collector for manual php session deletion

Question

I want to basically stop garbage collector from deleting my php sessions so that I can manually delete them myself under conditions. How would I go about stopping garbage collector?

Answer 1

In the INI set

session.gc_probability = 0

This can also be done with ini_set() but make sure you do it with every session_start() call.

Also, it's worth noting that several Linux distros have this as the default and there is a cron job cleaning up expired sessions.
