How can closures be used effectively for formula calculations in PHP?

Closures can be used effectively for formula calculations in PHP by encapsulating the formula logic within a closure function. This allows for the formula to be easily reused and passed around as a variable, making the code more modular and maintainable. 

// Define a closure function for a simple formula calculation
$calculateFormula = function($x, $y) {
    return ($x + $y) * 2;
};

// Usage example
$result = $calculateFormula(3, 4);
echo $result; // Output: 14
