如何将php数组划分为多维数组？请见下文

Question

我有如下所示的数组，这些数据来自具有动态字段的表单。

Array
(
    [package-name-1] => package1
    [package-serve-1] => sdasd
    [package-price-date-1] => 31-03-2020   
    [foodType-1-1] => Rice
    [foodTags-1-1] => rice
    [foodNotes-1-1] => notes
    [foodchoose-1-1] => 0
    [package-name-2] => package2
    [package-serve-2] => Leaf
    [package-price-date-2] => 12-08-2020
    [foodType-2-2] => rice1
    [foodTags-2-2] => rice1
    [foodNotes-2-2] => dasd
    [foodchoose-2-2] => 3
    [foodType-2-3] => rice2
    [foodTags-2-3] => rice2
    [foodNotes-2-3] => qwewe
    [foodchoose-2-3] => 0
)

我想要像下面这样的数组输出，就像在两个数组中一样，数组应该从包名键中分离出来，并移动到单独的数组中。产出应如下：

array(
  [0]=>array(
          [package-name-1] => package1
          [package-serve-1] => sdasd
          [package-price-date-1] => 31-03-2020   
          [foodType-1-1] => Rice
          [foodTags-1-1] => rice
          [foodNotes-1-1] => notes
          [foodchoose-1-1] => 0
       )
   [1]=>array(
          [package-name-2] => package2
          [package-serve-2] => Leaf
          [package-price-date-2] => 12-08-2020
          [foodType-2-2] => rice1
          [foodTags-2-2] => rice1
          [foodNotes-2-2] => dasd
          [foodchoose-2-2] => 3
          [foodType-2-3] => rice2
          [foodTags-2-3] => rice2
          [foodNotes-2-3] => qwewe
          [foodchoose-2-3] => 0
    )
)

你可以通过foreach()和strpos()来完成

$newArray = [];

$k = 0;
foreach($array as $key=>$value){

    if(strpos($key,'package-name') !== false){
        $explodedkeys = explode('-',$key);
        $id = end($explodedkeys);
        $k = $id-1;
    }
    $newArray[$k][$key] = $value;
}

print_r($newArray);
