PHP - Javascript/php Problem On Browser Close/unload Event

Hi there, I was wondering if it is possible to (on the closing of a browser to a logged in user) to automatically destroy that session. Thanks in advance.

I have a problem, where i need to know when user leave or close tha browser tab. I tryd to make a ajax post, after unload, make a POST into kill_browser.php and after 1 minute when session_expire, php code will be execute and save time into database. But it not seems to work :/ I'm glad if some 1 can say what im doing wrong, or is there eny better way to detect it.   @home.php   var leaved = 'leaved';
$(window).unload(
        function(){
            $.ajax({
            url: 'kill_browser.php',
            global: false,
            type: 'POST',
            data: leaved,
            async: false,
            success: function() {
            console.log('leaved');
            }
        });
    });   @kill_browser.php <?php

require('class/connection.php');
$conn = new connection();
session_cache_limiter('private');
$cache_limiter = session_cache_limiter();
session_cache_expire(1);
$cache_expire = session_cache_expire();
session_start();
$_SESSION['leaved'] = $_POST['leaved'];
if($_SESSION['leaved'] == null || $_SESSION['leaved'] == " "){
    $conn->logOut($_SESSION['userID'], $_SESSION['userIP'], $_SESSION['LAST_GENERATED_ID']);
    session_regenerate_id(true);
    unset($_SESSION);
    session_destroy();
    header('location:index.php');
}
?>

Good day!

I created a webpages and i have a login page consist of Username and Department. And i encountered problem in adding event in my calendar.

This is the flow of my webpage:
First I have a separate table for the user and calendar. In my user table it has a Username, Department, and Permission. In the permission I put True or False, only one user i put True because i want that user is the one who permitted to add event or if she is login the add event link appear, but if other login the add even0t did not appear.

This is my code in login:

<?php  
session_start();  
session_regenerate_id();  

if($_SESSION['loggedin']){  
//the user is already logged in, lets redirect them to the other page  
    header("Location:company.php");  
}  

//require_once 'conn.php';    
$db_name="dspi";  

mysql_connect("localhost", "root", "") or die("Cannot connect to server");  
mysql_select_db("$db_name")or die("Cannot select DB");     


        $department = mysql_real_escape_string($_POST['department']);     
        $username = mysql_real_escape_string($_POST['username']);  

        $sql=mysql_query("SELECT `Department`, `Username` FROM `tbllogin` WHERE `Department` = '{$department}' AND Username = '{$username}'") or die(mysql_error());  
        $ct = mysql_num_rows($sql);  
       
        if($ct == 1) {  
// im guessing this means that the user is valid.  
$_SESSION['loggedin'] = true; // now that the user is valid we change the session value.  
            $row = mysql_fetch_assoc($sql);    
             
            $_SESSION['username'] = $row['Username'] ; 
            $_SESSION['department'] = $row['Department']; 
             
            $Departments=array('Accounting', 'Engineering', 'Finishing_Goods', 'HRAD', 'MIS', 'Packaging_and_Design', 'Production', 'Purchasing_Logistic', 'QA_and_Technical', 'Supply_Chain'); 
             
            if (in_array($row['Department'], $Departments)){ 
                    header ('Location:company.php'); 
            }else{ 
                    echo "Incorrect Username or Department"; 
                    header ('Location:index.php'); 
            } 
        } 
?> 


and this is my code in calendar page:

<?php 

session_start(); 
$host = "localhost"; 

    $username = ""; 

    $password = ""; 

    $dbCnx = @mysql_connect($host, $username, $password) or die('Could not Connect to the database'); 

    $dbName = 'dspi'; 

    mysql_select_db($dbName);
