What are some best practices for commenting code in PHP, particularly in terms of syntax and language?

Issue: Commenting code in PHP is essential for improving code readability and maintainability. It is important to use clear and concise comments to explain the purpose of the code, its functionality, and any important details that may not be immediately obvious from the code itself. Example: 

// Issue: This function calculates the sum of two numbers
// Solution: Add comments to explain the purpose of the function and its parameters

/**
 * Calculate the sum of two numbers
 *
 * @param int $num1 The first number
 * @param int $num2 The second number
 * @return int The sum of the two numbers
 */
function calculateSum($num1, $num2) {
    // Add the two numbers together
    $sum = $num1 + $num2;
    
    // Return the sum
    return $sum;
}
