What is the significance of using parentheses in PHP code?

Using parentheses in PHP code is significant for grouping expressions, defining function parameters, and controlling the order of operations. It helps to make the code more readable and ensures that the intended logic is executed correctly. Example: 

// Using parentheses to group expressions
$result = (10 + 5) * 2;

// Defining function parameters with parentheses
function greet($name) {
    echo "Hello, " . $name;
}

// Controlling the order of operations with parentheses
$total = (10 + 5) * (2 + 3);
