Question

我有一个名为$results的数组，如下所示，

Array
(
    [0] => Array
        (
            [group_name] => Ist Term - LKG
            [group_id] => 69
            [parent_group_id] => 0
            [amount] => 3200
            [group_type] => I SEM TUTION FEES; II SEM TUTION FEES; SPORTS FEES; CONCESSION
            [group_amount] => 1000.00; 2000.00; 300.00; -100.00
        )

    [2] => Array
        (
            [group_name] => IInd Term - LKG
            [group_id] => 70
            [parent_group_id] => 0
            [amount] => 450.00
            [group_type] => MAGAZINE, PHOTOS,BAG, ID etc ; CO - SCHOLASTICS; BOOKS, NOTEBOOKS, UNIFORM
            [group_amount] => 200.00; 150.00; 100.00
        )

)

我正在表格中显示结果，

<?php echo
    '<table class="table table-bordered table-hover">

    <tr>

    <th>Group Name</th>
    <th>Group Type</th>
    <th>Group Amount</th>
    <th>Total Amount</th>
    <th>Actual Pay</th>

    </tr>';
    foreach($results as $key){

      echo
      '<tr>

       <td>' . $key['group_name'] . '</td>' .
      '<td>' . $key['group_type'] . '</td>' .
      '<td>' . $key['group_amount'] . '</td>' .
      '<td>' . $key['amount'] . '</td>' .
      '<td>' . 300 . '</td>' .

      '</tr>';

    }

    echo
    '</table>';

    ?>

表格结构如

此处总金额3200和450各自分别来自组金额的总和，

1000.00; 2000.00; 300.00; -100.00 => 3200

200.00; 150.00; 100.00 => 450

现在，在两个字段中，“实际支付”列的值为300，这意味着用户只能从总金额中支付300，因此我需要根据实际应付款显示值。 假设这里的实际应付款是300，并且组金额需要相应地从现有的组金额中分割出来，如下所示，以及我期望的期望输出，

第一组：

1000, 1900, 0, 0

第二组：

150, 0, 0

我需要根据实际工资在表格中显示如上所示的组数量，需要在组数量内分开。

请帮助我实现上面提到的结果，因为我是PHP的新手，我希望能有更多有用的支持来实现这一目标。任何好的帮助都会更加明显。

Answer 1

我已更新您的代码并编写了一些逻辑来计算组数量。请尝试这个：

 echo
    '<table class="table table-bordered table-hover">

    <tr>

    <th>Group Name</th>
    <th>Group Type</th>
    <th>Group Amount</th>
    <th>Total Amount</th>
    <th>Actual Pay</th>

    </tr>';
  $payamnt = 300;
    foreach($results as $key){
       $rest_amnt = $key['amount']-$payamnt;
       $group_amount = explode(" ",$key['group_amount']);
        $bramnt=array();
        foreach($group_amount as $gamt){
        $bramnt[] = rtrim($gamt,";");
        }
        $garr='';
        if(in_array($rest_amnt,$bramnt)){
       //print_r($bramnt);
       // echo count($bramnt);
        //echo $rest_amnt;
            $garr .=$rest_amnt;
            for($i=0;$i<count($bramnt)-1;$i++){
                   $garr .= ', 0';
            }
           // echo $garr;
        }else{
              $calval = $rest_amnt-$bramnt[0];
            $garr .=$bramnt[0];
            $garr .= ', '.$calval;
            for($i=0;$i<count($bramnt)-2;$i++){
                   $garr .= ', 0';
            }
            //echo $garr;
        }


      echo
      '<tr>

       <td>' . $key['group_name'] . '</td>' .
      '<td>' . $key['group_type'] . '</td>' .
     // '<td>' . $key['group_amount'] . '</td>' .
     '<td>' . $garr . '</td>' .
      '<td>' . $key['amount'] . '</td>' .
      '<td>' . 300 . '</td>' .

      '</tr>';

    }

    echo
    '</table>';

输出：

Group Name  Group Type  Group Amount    Total Amount    Actual Pay
Ist Term - LKG  I SEM TUTION FEES; II SEM TUTION FEES; SPORTS FEES; CONCESSION  1000.00, 1900, 0, 0 3200    300
Ist Term - LKG  I SEM TUTION FEES; II SEM TUTION FEES; SPORTS FEES; CONCESSION  150, 0, 0   450 300

Answer 2

此功能将在（pag）组中划分支付金额（考虑到组中的任何负数）并从每组中减去pag：

function getvals ($values = array(), $paid = 0) {
    if ($paid == 0) {
        return $values;
    }

    $paid = abs($paid);

    $i = 0;
    foreach ($values as $val) {
        if ($val <= 0) {
            $paid-=$val;
            continue;
        }
        $i++;
    }

    if ($i == 0) {
        return $values;
    }

    $frm = $paid / $i;

    foreach ($values as $val) {
        if ($val <= 0) {
          $data[] = 0;  
        } else {
          $data[] = round($val - $frm,2);
        }
    }

    return $data;
}


$values = array(1000,2000,300,-100);

$paid = 300;

$data = getvals($values, $paid);

print_r($data);

请你试试这个我试着用这个逻辑来解决你的问题：

echo
    '<table class="table table-bordered table-hover">

<tr>

<th>Group Name</th>
<th>Group Type</th>
<th>Group Amount</th>
<th>Total Amount</th>
<th>Actual Pay</th>

</tr>';
    foreach($results[0] as $key){

       $new_group_amount = getGroupAmount($key['group_amount'],300);

        echo
            '<tr>

   <td>' . $key['group_name'] . '</td>' .
            '<td>' . $key['group_type'] . '</td>' .
            '<td>' . $new_group_amount . '</td>' .
            '<td>' . $key['amount'] . '</td>' .
            '<td>' . 300 . '</td>' .

            '</tr>';

    }

    echo
    '</table>';


function getGroupAmount($group_amount,$actual_amount){


    $group_amount_array = array_reverse(explode(";",$group_amount));


    $balance = $actual_amount;
    foreach ($group_amount_array as $group_amount_arr ){


        if($balance > 0 ) {
            $new_group_amount [] = ($group_amount_arr > 0 && $group_amount_arr - $balance > 0) ? $group_amount_arr - $balance : 0;
        }else{

            $new_group_amount [] = $group_amount_arr;
        }
        $balance -=$group_amount_arr;


    }

   return  implode(";",array_reverse($new_group_amount));

}
