How can you apply the concept of percentage calculation to a real-world scenario using PHP code?

To apply the concept of percentage calculation to a real-world scenario using PHP, you can create a function that takes in the total value and the percentage you want to calculate. The function will then calculate the percentage value and return it. This can be useful for scenarios such as calculating discounts, taxes, or any other percentage-based calculations.

// Function to calculate percentage
function calculatePercentage($total, $percentage) {
    return ($total * $percentage) / 100;
}

// Example of calculating 20% of a total value
$totalValue = 100;
$percentage = 20;
$percentageValue = calculatePercentage($totalValue, $percentage);

echo "20% of $totalValue is $percentageValue";
