Apply value to a value from foreach loop PHP

本文关键字：一个应用 foreach 循环 PHP | 更新日期: 2023-09-27

我正在寻找一种解决方案，将折扣应用到基于项目的foreach循环的值，我的主要问题是，如果第二个项目满足要求，它也将应用于它，所以我想要的只是应用到第一个项目，找到了需求，然后传递到其他动作。

    echo '<pre>';
        $requeriment = 299;
        $items = array(
                        array(
                            'id' => 1,
                            'price' => 199,
                            'quantity' => 1
                        ),
                        array(
                            'id' => 2,
                            'price' => 399,
                            'quantity' => 1
                        ),
                        array(
                            'id' => 3,
                            'price' => 199,
                            'quantity' => 1
                        )
        );
        $flag = false;
        foreach($items as $item){
            $totalItem = $item['price'] * $item['quantity'];
            if($totalItem > $requeriment){
                if(!$flag){
                    $flag = true;
                    echo 'Disc 1% - ' . $item['id'];
                    echo "<br>";
                }else if($flag){
                    echo 'Disc 2% - ' . $item['id'];
                    echo "<br>";
                }
                continue;
            }
            echo 'Disc 2% - ' . $item['id'];
            echo "<br>";
        }
    //Ok, it found ID 2 with a value bigger than requirement and the job is done.
//Now if trough loop it not found item that meet the requirement 
//it need now to sum values to get the required value to meet the requirement
//and apply a 1% the the 2 items that made that sum, then apply 2% to the rest of ids.

是否有办法在同一循环中做到这一点?

  $i=0;
  foreach $items as $item{
   $i++;
  $totalItem = $item->price * $item->quantity;
if($totalItem > $requeriment){
//Apply a discount of 1%
    if($i==1){
     // for discount 1
    }elseif($i==2){
          // for discount 2
       }
  }

与其他折扣相同
