What are the best practices for handling tab selection and data retrieval in PHP forums?

When handling tab selection and data retrieval in PHP forums, it is best to use AJAX to asynchronously load content based on the selected tab without refreshing the entire page. This improves user experience by providing faster loading times and a more seamless browsing experience. 

// PHP code snippet to handle tab selection and data retrieval using AJAX

// Check for AJAX request
if(isset($_GET['tab'])){
    $tab = $_GET['tab'];

    // Retrieve data based on selected tab
    switch($tab){
        case 'tab1':
            // Code to retrieve data for tab 1
            break;
        case 'tab2':
            // Code to retrieve data for tab 2
            break;
        // Add more cases for additional tabs
    }

    // Return data as JSON response
    echo json_encode($data);
    exit;
}
