Starting a PHP SessionSession variables are stored in associative array called $_SESSION[]. These variables can be accessed during lifetime of a session. The following example starts a session then register a variable called counter that is incremented each time the page is visited during the session.
The Session Storage basically consists of 4 main methods. setItem(key, value): This method is used to set the value into the Session Storage based on the key. getItem(key): This method is used to get the value that is stored into the Session Storage. It takes a key and returns the value.
We can create the session by writing session_start() and destroy the session by using session_destroy(). You can access the session variable by writing $_session[“name”]. Let us understand how the session works from the following examples. Example 1: In the following, you can create the session by entering the name.

session_start();

$_SESSION['id'] = $someID;

$pid = $_SESSION['id'];
