session easy question

[itworks]

someone just told me that i need to put session_start(); in every page where i need to display or check a $_SESSION[] variable.

do i? i ask because i'm almost finishing a site where i only use session_start(); once when you first visit the index and then i don't use it anymore but all the $_SESSION[] variables are available across the site and i'm testing this in my local machine where register_globals is off.

thanks in advance.

Yes, you do have to call session_start on every page you want to session to be accessed on.

thanks for the quick answer LordShryku!

any idea why it's working without calling it everytime then? it's not that big of an issue since it's working and if i want to make sure i can always put the session_start() in all pages, there are not that many anyway but i would really like to know why.

Not without seeing the code and config. Might be because register globals is on and use cookies is also set, so you're getting it from a cookie value instead.

nevermind, i'm just silly.... forgot that i'm always including a verification file which has session_start(); ...... i'm sorry i had to waste your time, i guess i need to get more sleep :glare:

thanks again
