Muliple Session_Start()

[abdfahim]

Hi, I have some questions (for php 5.2.3)

 

1) Is there any problem if I use Session_Start() several times in a page?

 

2) Is there any other variables responsible for session expire except than session_destroy() and session_gc_maxlifetime() ?

yes why would you need it? secondly sessions must be sent prior to any output being sent

Ok. Then if I place

 

if (!isset($_SESSION)) {
session_start();
}

 

muliple times is there any problem?

why do you have to start the session over and over again?

and if you dont use ob start declaring session not on the top most will cause error

Well, I add those session_start() in each pages when I started php coding. Then i have to include some pages within other ones. As a result some (actually i think many) pages have multiple session_start. Now I have to do a lot to change those .

 

And btw, I am having some problems like my sessions expired in abt 5 mins without any reason though session.gc_maxlifetime is set to deafult 1440 in my server.
