What are the limitations of using AJAX requests to store tab IDs in session variables for PHP applications?

Storing tab IDs in session variables using AJAX requests can lead to scalability issues as the session data is stored on the server and can potentially grow too large. To solve this issue, consider storing the tab IDs in a database or using browser storage like localStorage instead. 

// Instead of storing tab IDs in session variables, store them in a database
// Example of storing tab IDs in a database table called 'user_tabs'

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "yourDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Assuming $tabID is the tab ID received from AJAX request
$tabID = $_POST['tabID'];

// Insert tab ID into database
$sql = "INSERT INTO user_tabs (tab_id) VALUES ('$tabID')";

if ($conn->query($sql) === TRUE) {
    echo "Tab ID stored successfully";
} else {
    echo "Error storing tab ID: " . $conn->error;
}

$conn->close();
