[PHP] Re: session id
The function session_start is sending a cookie. This means that you can't
echo anything before. Its the same rules as with setcookie.

[PHP] Re: session ID does not delete itself
in php.ini session.gc_probability= 1 ; percentual probability that the ; 'garbage collection' process is started ; on every session initialization session.gc_maxlifetime= 604800 ; after this number of seconds, stored ; data will be seen as 'garbage' and ; cleaned up by the gc process I have my php.ini set to everytime php is run it looks for session files 7 days (604800 seconds) old, if there are any files at all, there is a 1% chance php will delete them. this is called garbage collection. so to simply answer your question: no. they are not deleted when the user quits their browser. the cookie however can be set to a lifetime of 0, which means when the browser quits the cookie is considered expired and the browser on the next launch will delete the cookie. -- Chris Lee [EMAIL PROTECTED] Peter [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi, I have been experimenting with PHP4 using sessions and one of my books says that session ID's are created in the /tmp directory so I take a look in there and I find are about 10 sessions that have not been deleted dated earliest to about being week old ie. sess_5b30ccebb1d098c37a5e46efd7708fef I have been experimenting with user authentication with sessions and just plain starting a session when a user accesses the site. Well, the site is still experimental and each time I logged myself out. But I thought sessions were supposed to wipe themselves out from the /tmp directory immediately after leaving the website. Appreciate if someone could shed the light on this issue for me. Thanks.
