How can using parentheses in PHP code help improve readability and prevent syntax errors?

Using parentheses in PHP code can help improve readability by clearly indicating the order of operations in complex expressions. They can also prevent syntax errors by ensuring that the code is interpreted correctly by the PHP parser. By using parentheses, you can avoid ambiguity and make your code more understandable to other developers. Example:

// Without parentheses
$result = 10 + 5 * 2; // This may result in unexpected behavior

// With parentheses
$result = (10 + 5) * 2; // This ensures that addition is performed before multiplication
