PHP script: Display last session access time

PHP Cookies and Sessions: Exercise-15 with Solution

Write a PHP script to display the last time the session was accessed by the user.

Sample Solution:

PHP Code :

<?php
// Set the session save path
session_save_path('i:/custom/');
session_start();

if (isset($_SESSION['last_access_time'])) {
    $lastAccessTime = $_SESSION['last_access_time'];
    echo "Last access time: " . date('Y-m-d H:i:s', $lastAccessTime);
    $_SESSION['last_access_time'] = time(); // Update the last access time
} else {
    $_SESSION['last_access_time'] = time();
    echo "Session started. First access.";
}

?>

Sample Output:

Session started. First access.

Last access time: 2019-07-12 04:46:38

 
Last access time: 2019-07-12 04:46:59

Explanation:

In the above exercise -

We start the session using session_start() to initialize the session.

• Check if the session variable 'last_access_time' is set. If it is set, retrieve its value and store it in $lastAccessTime.
• Use echo to display the last access time using date() to format the timestamp into a human-readable date and time format.
• After displaying the last access time, we update the 'last_access_time' session variable with the current time using time() to record the new access time.

If the 'last_access_time' session variable is not set, we set it to the current time. We display a message indicating that the session has started and this is the first access.
