How can the complexity of PHP scripts be reduced to make them more manageable and easier to understand for beginners?

To reduce the complexity of PHP scripts for beginners, it's important to break down the code into smaller, more manageable functions, use meaningful variable names, and properly comment the code to explain its purpose. By organizing the code in a clear and structured manner, beginners can more easily understand and modify the script as needed.

// Example of a simplified PHP script with clear function names and comments

// Function to calculate the sum of two numbers
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}

// Function to display the result
function displayResult($result) {
    echo "The result is: " . $result;
}

// Main script
$num1 = 10;
$num2 = 5;
$sum = calculateSum($num1, $num2);
displayResult($sum);
