如何在php中再次重复相同的循环？

Question

我有以下foreach循环，我怎样才能再次重复相同的循环索引？

$n = 0;
$currentTotal = 0;
$currentSettlement = $coupons[0]->settlement_id;
foreach ($coupons as $coupon){
    if($currentSettlement == $coupon->settlement_id){
        $currentTotal += $coupon->amount;
    }else{
        $settlements[$n]['total'] = $currentTotal;
        $currentTotal = 0;
        $currentSettlement = $coupon->settlement_id;
        $n++;
        // after this I want to reiterate current loop from the beginning
    }

}

如果你想要必要的foreach循环，你可以使用你修复它只运行两次的函数：

$n = 0;
$currentTotal = 0;
$currentSettlement = $coupons[0]->settlement_id;
for2loop(1,$coupons);

function for2loop($loopagain,$coupons)
{

    foreach ($coupons as $coupon) {
        if ($currentSettlement == $coupon->settlement_id) {
            $currentTotal += $coupon->amount;
        } else {
            $settlements[$n]['total'] = $currentTotal;
            $currentTotal = 0;
            $currentSettlement = $coupon->settlement_id;
            $n++;
            if($loopagain == 1)
                for2loop(2,$coupons); // after this I want to reiterate current loop from the beginning
        }

    }
    return $currentSettlement
}

但我认为yu必须更喜欢while循环或更好地循环
