Sessions
I have a problem with session, I am using the following script script with sessions functionality but I am having the problem that as long as I refresh the session concept work fine, cookie sends the PHPSESSID val(val of count increments that is what the script does if the session exists),
but simeltaneously when I run a new instance of the browser and type the URL for php script again then it seems as if PHP creates a new session for me ( and takes count 0 i.e the session does not exist and a new sesssion is created, I have not closed the earlier browser).
I will be very thankful to you if you can help me to understand why it does not send the PHPSESSID(why there is a new sesssion everytime when I have this URL run in new instance of browser and not the same session).
<?php
// Initialize a session. This call either creates
// a new session or re-establishes an existing one.
session_start();
// If this is a new session, then the variable
// $count will not be registered
if (!session_is_registered("count"))
{
session_register("count");
session_register("start");
$SESSION["count"] = 0;
$SESSION["start"] = time();
}
else
{
$_SESSION["count"]++;
}
$sessionId = session_id();
?>
