How can recursion be effectively implemented within a class function in PHP to return a value?

To implement recursion within a class function in PHP to return a value, you can create a method within the class that calls itself recursively until a base condition is met. This base condition should be used to stop the recursion and return a final value. By structuring the recursive function properly, you can effectively utilize recursion within a class function in PHP. 

class RecursiveClass {
    public function recursiveFunction($n) {
        if ($n == 0) {
            return 1; // Base condition to stop recursion
        } else {
            return $n * $this->recursiveFunction($n - 1); // Recursive call
        }
    }
}

$recursiveObj = new RecursiveClass();
echo $recursiveObj->recursiveFunction(5); // Output: 120
