How can debugging techniques be applied to troubleshoot issues with recursive functions in PHP?

When troubleshooting recursive functions in PHP, one common issue is the function not terminating properly, causing it to run indefinitely and potentially leading to a stack overflow error. To solve this, you can add a base case that explicitly defines when the function should stop recursing. Additionally, you can use debugging techniques such as printing out the function arguments and return values at each recursive call to track the flow of the function and identify any potential issues. 

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

    // Recursive call
    echo "Current value: $n\n";
    recursiveFunction($n - 1);
}

recursiveFunction(5);
