What is the best practice for handling notifications to users in PHP applications?

When handling notifications to users in PHP applications, it is best practice to use a session variable to store the notification message and then display it to the user on the next page load. This ensures that the notification is only shown once and is not lost during page redirects. 

// Set notification message in session variable
$_SESSION['notification'] = 'Your message here';

// Display notification to user
if(isset($_SESSION['notification'])){
    echo $_SESSION['notification'];
    unset($_SESSION['notification']); // Clear the notification after displaying it
}
