[PHP] session.gc_probablity From: Damian Sobieralski (dsobiera <email protected>)
Date: 06/29/01

Hi,

 I am running PHP 4.0.5 as an Apache Module (with Zend Optimizer) on NT 4.0
 SP6 and have been very happy with it. Until we think about using Easysoft
 solution the only method we have to get into our HP3000 is a Windows'
 based ODBC one (which works well). Okay, so I explained why I am running PHP on
 NT :) The question I am having is I wrote my own session handler to
 store in a MySQL database. All works well. But I noticed in 4.0.3 pl1 the
 gc_probability of garbage collection routine being called doesn't work right.
 Anything below 75 in the php.ini file would have it not being called at
 all (i put in a print statement to let me know when it was being called).
 Anything over 75 had it called on EVERY session_start(). I upgraded to
 4.0.5 and now it only gets called when the probability in the php.ini file
 is set >= 99 . I was okay with the overhead of the gc being
 called every time with 4.0.3 but with the 99 limit now....it may only take one more
 release until it is never called :-)

  Anyone know what is going on with the NT Apache PHP?

 BTW- I call a script which has phpinfo() to make sure it is reading the
 correct php.ini file (C:\WINNT\php.ini.... and it is and the probability
 value is set correctly).

 Any advice?
