What alternative approach can be used instead of determining variable names within a function in PHP?

When determining variable names within a function in PHP, it can lead to potential naming conflicts and make the code harder to maintain. An alternative approach is to pass the variables as arguments to the function, allowing for better encapsulation and reusability. 

// Instead of determining variable names within a function, pass them as arguments

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

// Call the function with specific variables
$result = calculateSum(5, 10);
echo $result; // Output: 15
