How can PHP developers efficiently update language settings without the need for manual page reloads?

To efficiently update language settings without manual page reloads, developers can use AJAX to send requests to the server and update the content dynamically. This allows for a seamless user experience without the need for page reloads. 

<?php
// Check if a language change request has been made
if(isset($_POST['language'])){
    // Update session language variable
    $_SESSION['language'] = $_POST['language'];
    // Return success response
    echo json_encode(['status' => 'success']);
    exit;
}

// Sample AJAX request to update language settings
// This can be triggered by a button click or other user action
?>
<script>
    // Sample AJAX request to update language settings
    $.ajax({
        url: 'update_language.php',
        type: 'POST',
        data: { language: 'en' }, // Set the language to update
        success: function(response){
            // Handle success response
            console.log(response);
        },
        error: function(xhr, status, error){
            // Handle error response
            console.error(error);
        }
    });
</script>
