Are there specific best practices to follow when implementing recursion in PHP to avoid infinite loops?

When implementing recursion in PHP, it's crucial to have a base case that will stop the recursive calls and prevent infinite loops. Make sure to carefully design your recursive function so that it progresses towards the base case with each recursive call. Additionally, consider using conditional statements to check for valid input parameters to avoid unexpected behavior. 

function recursiveFunction($n) {
    // Base case to stop the recursion
    if ($n <= 0) {
        return;
    }

    // Recursive call with updated parameter
    recursiveFunction($n - 1);
}

// Call the recursive function with an initial parameter
recursiveFunction(5);
