php sessions vars expiry all same time

php sessions vars expiry all same time, or depends when each get setuped and each may expiry differ time than one other session var ?

PHP Sessions all delete at the same time:

session_start(); // essential
$_SESSION['date'] = time(); //find out date with mktime()
$_SESSION['day'] = date('l'); //date, for example "Sunday" 

These will both end at the same time. Now, perhaps we want one to end before the session is closed, we will use unset(), unset() unsets a variable.

session_start(); // essential
$_SESSION['date'] = time(); //find out date with mktime()
$_SESSION['day'] = date('l'); //date, for example "Sunday"
if($_SESSION['day'] == "Wednesday") { //if the day equals wednesday
unset($_SESSION['day']); //unset it
}
if(isset($_SESSION['day'])){ //if the say session exists
echo "Today isn't Wednesday";
}
else { //if it doesn't
echo "Today is Wednesday";
} 

This is just an example of a session ending earlier then another.
