Use the following function to find the percentage value of one number to another. If the $total parameter is zero then zero is returned as this would otherwise result in a division by zero error.

function get_percentage($total, $number) { if ( $total > 0 ) { return round($number * ($total / 100),2); } else { return 0; } }

Here are some examples of the function in action.

echo get_percentage(100,50).'%'; // 50% echo get_percentage(100,10).'%'; // 10% echo get_percentage(100,100).'%'; // 100% echo get_percentage(400,3).'%'; // 0.75% echo get_percentage(1234,4321).'%'; // 350.16%

## Comments

I just had to swap $total and 100 over for my purposes, i.e returning 100/200 as 50%.
