【问题描述】：

我有一个数组，如下所示

[0] = Array
    (
        [title] =&gt; Khamna,
        [booking_number] = 200003852,
        [quantity] =1,
        [unit_price] = 5.00,
        [gross_total] = 5.00,
    )

[1] = Array
    (
        [title] = Khamna
        [booking_number] = 200003857
        [quantity] = 2
        [unit_price] = 5.00
        [gross_total] = 410.00
    )

[2] = Array
    (
        [title] = Khamna
        [booking_number] = 200003857
        [quantity] = 2
        [unit_price] = 200.00
        [gross_total] = 410.00
    )

[3] = Array
    (
        [title] = Khamna
        [booking_number] = 200003858
        [quantity] = 1
        [unit_price] = 200.00
        [gross_total] = 200.00
    )

我希望结果输出，例如 booking_number 将是数组的键，子数组将基于“unit_price”和“quantity”.. unit_price 和数量作为子数组大于 1 或 2 或 3

[200003852] => Array
    (
        [title] =Khamna
        [gross_total] = 5.00
        [detail] = Array
            ( 0 => array([quantity] = 1
                [unit_price] = 5.00),
        )

    )

[200003857] = Array
    (
        [title] = Khamna
        [gross_total] = 410.00,
        [detail] = Array
            ( 0 => array([quantity] = 2
                [unit_price] = 5.00),
              1 => array([quantity] = 2
                [unit_price] = 200.00),                 
            )
    )

[200003857] = Array
    (
        [title] = Khamna
        [gross_total] = 10.00
        [detail] = Array
            ( 0 => array([quantity] = 2
                [unit_price] = 5.00),

            )
     )

【问题讨论】：

只需迭代您的数组并创建一个看起来像您想要的方式的新数组。到目前为止，您尝试过什么？

标签： php arrays

【解决方案1】：

这会帮助你...

$result = array();
foreach($array as $row) {
    if(!isset($result[$row['booking_number']])) {
        $result[$row['booking_number']] = array(
            'title' => $row['title'],
            'gross_total' => $row['gross_total']
        );
    } 
    $result[$row['booking_number']]['details'][] = array(
        'quantity' => $row['quantity'],
        'unit_price' => $row['unit_price']
    );
}

【解决方案2】：

此代码将帮助您。

$res = [];
foreach($array as $v){
  $res[$v['booking_number']] = 
  [
  'title'=>$v['title'],
  'gross_total'=>$v['gross_total'],
  'detail'=>[['quantity'=>$v['quantity']],
             ['unit_price'=>$v['unit_price']]]
  ];
}
echo '<pre>'; print_r($res);

【解决方案3】：

在你的原始数组之后运行它

foreach ($arra as $key) {
 $arr[$key['booking_number']]=array('title'=> $key['title'],'gross_total'  
     =>$key['gross_total'],'detail'=>array('0' => 
     $key['unit_price'],'1' => $key['quantity']) );

         }

注意：$arra 是你的原始数组

它将使用 echo "<pre>"; print_r($arr); 像这样打印您的数组

    Array
(
    [200003852] => Array
        (
            [title] => Khamna
            [gross_total] => 5
            [detail] => Array
                (
                    [0] => 5
                    [1] => 1
                )

        )

    [200003857] => Array
        (
            [title] => Khamna
            [gross_total] => 410
            [detail] => Array
                (
                    [0] => 5
                    [1] => 2
                )

        )

)
