Turning this into a function (Beginner Level)

[Jason]

I need some help writing the following lines of code into a simple
function. I'd like to be able to create a function to do the
calculation, then feed the $a, $b, or $c variable into it.

Thanks,
J

<?php $a = $kerryvotes/$votes;
$kpercentage = $a * 100;
$kpercent = round($kpercent age, 0);
?>

<?php $b = $bushvotes/$votes;
$bpercentage = $b * 100;
$bpercent = round($bpercent age, 0);
?>
<?php $c = $nadervotes/$votes;
$npercentage = $c * 100;
$npercent = round($npercent age, 0);
?>

function votepercent($vo tes, $totalvotes) {
$total = round(($votes/$totalvotes)*10 0);

Use example:
echo 'Kerry has yer '.votepercent($ quantityforkerr y, $totalofvotes). ' %
of the votes';

You needn't do it one by one ...
Here's a function to do it all in one swoop :-)


<?php
function calc_percentage s($individual_v otes) {
$sum = array_sum($indi vidual_votes);
foreach ($individual_vo tes as $k=>$v) {
$ret[$k] = round($v/$sum*100);
}
return $ret;
}

/* example usage */

/* disclaimer: the numbers are random */
$votes = array('bush'=>5 55, 'kerry'=>555, 'nader'=>555);

$percs = calc_percentage s($votes);
print_r($percs) ;
?>
