How can deprecated functions like create_function() in PHP be updated to avoid error messages?

The deprecated function create_function() in PHP can be updated to avoid error messages by using anonymous functions instead. Anonymous functions provide a more modern and efficient way to achieve the same functionality without relying on deprecated features. 

// Using anonymous functions to replace create_function()
$addNumbers = function($a, $b) {
    return $a + $b;
};

// Calling the anonymous function
echo $addNumbers(5, 3); // Output: 8
