По съкратен вариант на този код?

[nom3r1]

Има ли няк'в по съкратен вариант за кода по-долу ?

if($total < 21) {
	$total_end = $total+7;
	$dostavka = 7;
} elseif ($total < 31) {
	$total_end = $total+6;
	$dostavka = 6;
} elseif ($total < 41) {
	$total_end = $total+5;
	$dostavka = 5;
} elseif ($total < 51) {
	$total_end = $total+4;
	$dostavka = 4;
} elseif ($total < 61) {
	$total_end = $total+3;
	$dostavka = 3;
} elseif ($total < 71) {
	$total_end = $total+2;
	$dostavka = 2;
} elseif ($total < 81) {
	$total_end = $total+1;
	$dostavka = 1;
} elseif ($total > 82) {
	$total_end = $total;
	$dostavka = 0;
} else {
	$total_end = $total;
	$dostavka = 0;
}

$dostavka = 0;
for($i=2;$i<=8;$i++) {
if($total < (10*$i +1)) {
$dostavka = 9 - $i;
break; }}
$total_end = $total + $dostavka;
