What are the potential pitfalls of using round brackets in PHP code, and how can they be managed effectively?

Using round brackets in PHP code can lead to syntax errors if not used correctly, especially when dealing with function calls, conditionals, or expressions. To manage this effectively, it's important to ensure that opening and closing brackets are properly matched and nested. Additionally, using proper indentation and code formatting can help improve readability and reduce the chances of making mistakes.

// Example of properly using round brackets in PHP code
if (($a + $b) > $c) {
    echo "Sum of a and b is greater than c";
}
