[PHP] Session's is slowing the page ??
Hello,
I have very wierd problem :
I use session to manage users and I have this structure of the page :
-
include("db.php");
include("header.php");
bla bla
include("footer.php");
-
in the db.php I have :
session_start();
#some mysql connect stuff
I use session with the $_SESSION array (cheking if registered[isset($_S...)]
and registering...)
and all work fine
but sometimes the page loading is very very very slow (and its a really
really fast host) and when I removing session_start(); from the top of the
page, the page load normaly.
the PHP version is 4.1.1, someone have an idea ?
thanks in advance,
Dima.

Hi Tom
Thanks for your help but the problem still happens :-(
First I tried to use session_readonly() but it was unknown FUNC` in my php,
then I try the second way :
I have header.php & footer.php in the header I use session_start(); and in
the footer I use session_write_close() and still every minute the site
"freezes".
Is there any other way ? I really need to use these session's...
thanks again for your great help,
Dima.
