What steps can be taken to improve the code structure and readability in PHP?

To improve code structure and readability in PHP, it is important to follow best practices such as using meaningful variable names, organizing code into functions and classes, commenting code effectively, and adhering to a consistent coding style. 

// Example of improved code structure and readability

// Define a class for better organization
class Calculator {
    // Use meaningful method names
    public function add($num1, $num2) {
        return $num1 + $num2;
    }

    public function subtract($num1, $num2) {
        return $num1 - $num2;
    }
}

// Instantiate the class and use the methods
$calculator = new Calculator();
$result = $calculator->add(5, 3);
echo $result; // Output: 8
