note 61117 deleted from ref.session by danbrown

Note Submitter: james dot ellis at gmail dot com ---- If you are wondering why your garbage cleanup method is not being called, read on. The manual notes for garbage cleanup state that the session.gc_divisor defaults to 100: [code] //http://php.net/manual/en/ref.session.php session.gc_probability ... Defaults to 1. session.gc_divisor .... session.gc_divisor defaults to 100. [/code] This would provide a gc probability of 1 in 100 ie. your garbage cleanup is going to be called 1% of the time. Conversely, my PHP 5.1.1 install, compiled from source, contains this in the php.ini-recommended file (and my php.ini file): [code] ; Define the probability that the 'garbage collection' process is started ; on every session initialization. ; The probability is calculated by using gc_probability/gc_divisor, ; e.g. 1/100 means there is a 1% chance that the GC process starts ; on each request. session.gc_probability = 1 session.gc_divisor = 1000 [/code] A 0.1% probability by default. Based on the information provided, I set my gc_probability to 100, thus providing a 1% probability stale sessions would be culled. Moral:your local php.ini may differ from what the manual provides.
