Why are clear and descriptive function names important for understanding the logic behind recursive functions in PHP?

Clear and descriptive function names are important for understanding the logic behind recursive functions in PHP because they provide a clear indication of what the function is doing at each step of the recursion. This helps developers follow the flow of the recursive calls and understand the purpose of the function without having to dive into the implementation details. 

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