How can PHP be used to calculate percentages based on given numbers?

To calculate percentages based on given numbers using PHP, you can use the formula: (part/total) * 100. First, determine the part and total values you want to calculate the percentage of. Then, plug these values into the formula to get the percentage result.

$part = 25; // Example part value
$total = 100; // Example total value

$percentage = ($part / $total) * 100;

echo "The percentage is: " . $percentage . "%";
