What is the best practice for creating functions that clone and modify existing PHP functions?

When creating functions that clone and modify existing PHP functions, it is important to maintain the original functionality while adding new features or modifications. One approach is to use the `extend` keyword to create a child class that inherits from the parent class containing the original function. This allows you to override the original function with your modified version while still accessing the parent function if needed. 

class CustomFunction extends OriginalFunction {
    public function modifiedFunction($param) {
        // Add your custom modifications here
        // Call the parent function if needed
        parent::originalFunction($param);
    }
}

// Example of how to use the custom function
$customFunction = new CustomFunction();
$customFunction->modifiedFunction($param);
