Note Submitter: php-comment-NOSPAM-2004@ryandesign.com ---- Oh, how I wish I had read this sentence on this page before wasting hours today: "The keys in the $_SESSION associative array are subject to the same limitations as regular variable names in PHP, i.e. they cannot start with a number [...]" So, don't do <?php $_SESSION[0] = "whatever"; ?> and expect "whatever" to be available on the next page. Also to expand on what "christophe" mentioned on 18. Dec 2003 about garbage collection, in fact garbage collection occurs (100 * session.gc_probability / session.gc_divisor) percent of the time a visitor calls up a page which uses sessions. By default, this is once every 100 page requests, on average. If you wanted garbage collection to occur once every 1000 requests, you'd keep gc_probability at 1 and set gc_divisor to 1000. What remains unclear to me is the definition of session.gc_maxlifetime. Is a session considered "garbage" when the current time is this many seconds after the session was created, or this many seconds after it was last accessed?
