Question about getting session vars

[kathycam]

Hello

I have created this function to set a session variable with a random number (just to see if I anything was working):

function StartSession()
{
session_unset();
session_destroy();
$_SESSION = array();

session_start();
$sSessionID = rand(RAND_START,RAND_END);
session_register('$sSessionID');
}

Then I try to call it:
echo "Sessions = ". $_SESSION['$sSessionID'];

and nothing is set.

How do I do this?

Thanks.

...you're doing a lot of unnecessarily complicated and somewhat counter-productive stuff. For example, you don't really need to use a custom function to start your session. Then, your StartSession() function destroys any existing session - you're starting a new session each time. Third, the code you posts doesn't actually start a session (you never call your function).

<?php
// you need to start your session _before_ any output to the user.
// unless you _need_ a custom session id, just let PHP create one itself.

// start the session.
session_start();

// (don't use session_register(). it is deprecated and was actually removed in 5.4.)

// using session variables:
if( empty( $_SESSION ) ){
    //    if no session exists (i.e., this is the first page visit),
    //    we'll start with a value of 1.
    $_SESSION['view_count'] = 1;
}else{
    //    if a session exists, we'll increment the view count.
    $_SESSION['view_count']++;
}
// then print out how many page views there have been this session:
print "Number of times you have viewed this page during this session: {$_SESSION['view_count']}";

Thanks #Traq this quite sufficient reply from you I know

Two ways : 1. manually write each page session_start()

2. all site level set value 1 in php.ini file session_auto_start()
