Why is it recommended to return values instead of using echo statements within a function in PHP?

Returning values instead of using echo statements within a function in PHP is recommended because it allows for better separation of concerns. By returning values, the function can be used for further processing or manipulation by other parts of the code, making it more versatile and reusable. Echo statements directly output content to the browser, which can limit the flexibility of the function. 

function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Example usage
$sum = calculateSum(5, 3);
echo $sum; // Output: 8
