How can PHP be used to calculate percentages and limit the output to two decimal places?

This function allows you to format a number with a specific number of decimal places. You can calculate the percentage by dividing the part by the total and then multiplying by 100. Finally, use number_format() to limit the output to two decimal places. 

$part = 25;
$total = 100;
$percentage = ($part / $total) * 100;
$percentage = number_format($percentage, 2);
