Is recursion or iteration a better approach for solving the given problem in PHP?

The given problem involves calculating the factorial of a number. Recursion can be a better approach for solving this problem as it simplifies the logic and makes the code more concise. By using recursion, we can repeatedly call the function with a smaller input until we reach the base case. 

function factorial($n) {
    if ($n <= 1) {
        return 1;
    } else {
        return $n * factorial($n - 1);
    }
}

// Example usage
echo factorial(5); // Output: 120
