How can a PHP developer ensure that they are following best practices when working with functions, especially if they have not used them in a while?

To ensure that a PHP developer is following best practices when working with functions, especially if they have not used them in a while, they can refer to the PHP documentation for guidance on function usage and best practices. Additionally, they can utilize coding standards and guidelines, such as PSR-1 and PSR-2, to ensure consistency and readability in their code. 

<?php

// Example function following best practices
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Calling the function
$result = calculateSum(5, 3);
echo $result; // Output: 8

?>
