How do you document PHP projects effectively to ensure future understanding and maintenance?

To document PHP projects effectively for future understanding and maintenance, it is essential to use clear and concise comments throughout the code to explain the purpose of each function, class, and method. Additionally, creating a README file that outlines the project structure, dependencies, and how to run the code can be helpful. Using version control systems like Git and regularly updating documentation can also aid in maintaining the project. 

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