How can developers ensure they remember the functionality of their PHP scripts to avoid confusion in the future?

To ensure developers remember the functionality of their PHP scripts, they can add comments within the code to explain the purpose of each section or function. Additionally, developers can create a documentation file outlining the overall structure and functionality of the script. This will help avoid confusion in the future and make it easier for developers to maintain and update the code. 

<?php

// This function calculates the sum of two numbers
function calculateSum($num1, $num2) {
    // Add the two numbers together
    $sum = $num1 + $num2;
    
    // Return the sum
    return $sum;
}

// Example usage of the calculateSum function
$result = calculateSum(5, 10);
echo "The sum is: " . $result;

?>
